I met a young man at a party many years gone by who boasted to a small gathering in some downtown Toronto townhouse kitchen, late in a summer’s evening over Heineken, that he could refute Marxism in one sentence. I scoffed but was intrigued as many of us there were—though quite a few I might add, left the kitchen like he had covid.

This was his one sentence refutation: “I could instruct a hunter-gatherer, chimpanzee, robot, American factory worker, or whoever, to turn and tighten this and that, on the this-or-that assembly line, but to instruct the factory worker, create the robot, invent the machine they assembled, to think up the idea of the assembly line, to be the primatologist to coach the monkey, anthropologist to initiate the hunter-gather, all these types of activities, take mental acuity and human accumulated knowledge after years of arduous study in one form or another; so much for The Labour Theory of Value (Surplus Value).”

We were all I suppose, deflated, but of course with hindsight, it was quite true, he had refuted Marxism in one sentence with  The Theory of  Human  Capital, or at least what we usually mean by unionized or organized labour. Of course mental labor is nonetheless real labour even if Adam Smith and Karl Marx didn't understand that wealth indeed is mostly created by human cleverness, i.e, Human Capital.

If there was ever any doubt that Marxism was a religion, you just had to spend several evenings with some of them to realize it. Indeed, one of the hardest, bravest, and most courageous things to be in the West, is a Marxist in Canada, (just joking), which is why we have spawned so many of the armchair-variety. At a large gathering of Marxists and Communists one evening just years before the fall of the wall, one of their stars was describing in a dinner speech, a radio interview he'd had on air that day. The interviewer, he claimed was a fascist, who everyone knew perfectly well was a democrat, a human rights activist, and an elected member of The Liberal Party of Canada - it sounded like what a Christian would call a Roman heathen or a Moslem, an unbeliever. They didn't suspect someone so critical of their beliefs was in their midst or they didn't care. I was there as the lover of their darling beauty, and they waxed poetic all night as they drank red wine and dreamt of violent revolution.
Marxist feudalism replaced rule of law, which had been influenced and restrained by market forces and propertied parties even in the most nationalistic autocracies, into the terror of the total lethal state: all human freedom of choice was halted anywhere that militant socialists came to power. To quote the Chinese astrophysicist Fang Lizhi: “If every one of those good words — liberty, equality, fraternity, democracy, human rights — has been called 'bourgeois', what on earth does that leave for us” [in communist China]? Everywhere, with few exceptions, where the Procrustean communists gained enough power to carry out revolution and collectivize farmland, they produced famine. Everywhere, with no exceptions, where fundalmentalist Marxists gained total ideological control, they murdered their intellectual enemies with ghastly methods and in unbelievable numbers.
That same night, the speaker's wife, after a few more glasses, called Marxists everywhere in the world, scientists. It was hard not to laugh out loud. She'd come from Iraq and worked in a factory in Pickering where she was fighting with management to set up a union. She hadn't finished high school and could no more name the four Galilean moons than the millions killed in the Soviet's slave labor camps, nor did she know who Stephen Hawking or Max Planck were, and when asked about Darkness at Noon, she responded that Koestler was insane and when The Gulag Archipelago was thrown into the conversation, she swore that Solzhenitsyn was nothing but a liar.
The Marxist's contention is that there is no God, but Marx started an intellectual and political crusade not for a healthy exchange of ideas, but as a closed cause without dissent and as a tool for violence. As a young man in Prussia in the 1830's he witnessed firsthand Liberalism and political freedom, and as a mature thinker (much as Plato had done before him), he went running for autocracy. He planned to replace private religion with a totalitarian governmenta church of the state where the worker-proletariat, (the oppressed), would be sanctified. The owner-capitalists, (the Satan-lovers), and the middle-class bourgeoisie, (the sinners), would be condemned and the inheritors of the new body politic would be rewarded in perpetuity in the paradise of the dictatorship with Marx as the prophet-messiah. He was the last word in historical materialism, the process where pure goodness in the guise of the exploited, overthrow the evil idiot-class and become egalitarian in a violent seizure of political power. It was inescapable, inexorable, unstoppable, and humankind was trapped inside of it, but lucky for us, the benevolent Marx and his followers were so brilliant that they developed a special kind of logic - dialectical logic - which lifted them above it all. Thus was born their conceit, and the millions who were lost in the reconstruction? ... Grist for the grinder (to quote Stalin).
If you think Mohammed and Christ are the only Prophets to Spread Hatred
Read The Following Quotes from Marx's private letters.
 “What is the worldly religion of the Jew? Huckstering. What is his worldly God? Money... Money is the jealous god of Israel, in face of which no other god may exist. Money degrades all the gods of man - and turns them into commodities.. The bill of exchange is the real god of the Jew. His god is only an illusory bill of exchange. The chimerical nationality of the Jew is the nationality of the merchant, of the man of money in general.”
"The workers must, above all, during the conflict and immediately after the struggle, counteract, as much as possible, bourgeois efforts to calm things down and force the democrats to carry out their current terrorist phrases. They must work towards ensuring [that] the immediate revolutionary excitement not be suppressed right after the victory of the revolution. Just the opposite, they must attempt to keep it up. Far from opposing so-called excesses, examples of the people’s revenge on hated individuals or public buildings connected with hateful memories, they must not just tolerate such excesses but take over the leadership of them."
“Thus we find every tyrant backed by a Jew, as is every pope by a Jesuit. In truth, the cravings of oppressors would be hopeless, and the practicability of war out of the question, if there were not an army of Jesuits to smother thought and a handful of Jews to ransack pockets.”
“The real work is done by the Jews, and can only be done by them, as they monopolize the machinery of the loan-mongering mysteries by concentrating their energies upon the barter trade in securities. Here and there and everywhere that a little capital courts investment, there is ever one of these little Jews ready to make a little suggestion or place a little bit of a loan. The smartest highwayman in the Abruzzi is not better posted up about the locale of the hard cash in a traveler's valise or pocket than those Jews about any loose capital in the hands of a trader. The language spoken smells strongly of Babel, and the perfume which otherwise pervades the place is by no means of a choice kind.”
“Thus do these loans, which are a curse to the people, a ruin to the holders, and a danger to the governments, become a blessing to the houses of the children of Judah. This Jew organization of loan-mongers is as dangerous to the people as the aristocratic organization of landowners. The fortunes amassed by these loan-mongers are immense, but the wrongs and sufferings thus entailed on the people and the encouragement thus afforded to their oppressors still remain to be told.”
“The fact that 1,855 years ago Christ drove the Jewish moneychangers out of the temple, and that the moneychangers of our age enlisted on the side of tyranny happen again chiefly to be Jews, is perhaps no more than a historical coincidence. The loan-mongering Jews of Europe do only on a larger and more obnoxious scale what many others do on one smaller and less significant. But it is only because the Jews are so strong that it is timely and expedient to expose and stigmatize their organization.”
"The restless never-ending process of profit making alone is what he [the Capitalist] aims at. This boundless greed after riches, this passionate chase after exchange-value, is common to the capitalist and the miser; but while the miser is merely a capitalist gone mad, the capitalist is a rational miser. The never ending augmentation of exchange value, which the miser strives after, by seeking to save his money from circulation, is attained by the more acute capitalist, by constantly throwing it afresh into circulation."
“The Jewish Nigger Lassalle, who fortunately leaves at the end of this week, has happily again lost 5,000 Thaler in a fraudulent speculation. The fellow would rather throw money in the dirt than make a loan to a 'friend' even if interest and capital are guaranteed. He acts on the view that he must live like a Jewish baron or baronised Jew."
"At all events, I hope the bourgeoisie will remember my carbuncles until their dying day. What swine they are!"
Democide figures for the 20th Century communists regimes are calculated between 60 to 150 million murders, see here: ( 1,  2,  3,  4,  5,  6,  7,  8,  9, 101112, 13), so indeed, the Jews and the Bourgeoisie paid in full for Marx's boils. Robert Conquest's monumental work on Stalinist horrors, The Great Terror, earned enormous animosity upon its initial release in 1968—its graphic descriptions of the horrors perpetrated in the Soviet Union under Stalin's direction were felt by many to be false in virtually every particular. The opening of the Soviet archives and later verification by a host of Russian historians not only supported Conquest's findings, but showed the Stalin's “model state” had been even worse than Conquest had originally outlined. When The Great Terror was rereleased in a post-glasnost 1992 edition, [Link # 3 in this paragraph], Conquest was asked if he would like to give it a new title. His terse response was: “How about, I Told You So, You Fucking Fools.” Quoted from, Evil Genes. And also from the same book: "historian R. J. Rummel writes: “For perspective on Mao's most bloody rule, all wars [worldwide] 1900–1987 cost in combat dead 34,021,000—including WWI and II, Vietnam, Korea, and the Mexican and Russian Revolutions. Mao alone murdered over twice as many as were killed in combat in all these wars.” He also killed nearly four times as many as are thought to have died in four hundred years of the African slave trade, from capture to sale in Arab, Oriental, or New World markets.
While remembering that Marx had a secular Jewish heritage, (raised as a Christian, most certainly studied Plato and joined the Hegelians in youth), one must wonder here that it is not the "Jew" per se but the tone of rancour toward wealth and materialism in general which underscores Marxism as "A Philosophy of Resentment" much as it does for other Platonist beliefs such as Catholicism and Existentialism. To quote Marx, “Even the greatest sage of antiquity, the divine Plato, speaks in more than one place of a deep yearning for a higher being, whose appearance the unsatisfied aspiration to truth and light fulfills." It is safe to remark at this point in time that no one in history has been more responsible than Marx for so much murder and mayhem except for perhaps Plato himself. Marx's resentment of wealth was a typical 18th Century hatred for all middlemen-trader minorities who out-worked and out-performed the majorities where they settled, almost all genocides have been against these groups.
"Karl Popper did not want to deal with the question he found the means to explain. [Marxism’s durability through most of Popper’s lifetime] And I wondered whether its very durability had not induced in him a kind of fatalism or frustration. In the end, what is the use of understanding an error, if it goes on being repeated? Popper did not want to deal with the question directly, except by making one point that again went over the arguments against historicism. [Historicism is the false inveighing of teleological ends into history, or the historical belief that “our story” is predetermined by some factor (usually economics, context or Zeitgeist) and humankind has no real freedom. Paraphrased from F Hayek]. Someone might, in fact, think of him as a man who waited on the river bank for the corpses of his enemies to float by. But no part of this image applies to Karl Popper: neither the corpses nor the enemies, and especially not the river. Not the corpses, because he regarded non-violence as a cornerstone of civilization. Not the enemies, because the friend-enemy polarization of history and politics is precisely one of the main things he holds against Marxism. And not the river, because Popper considers the idea of history as a watercourse with a known source and mouth to be responsible for a huge number of crimes." Lessons of This Century
From “Marx The Prophet”, Capitalism, Socialism and Democracy: It was not by a slip that an analogy from the world of religion was permitted to intrude into the title of this chapter. There is more than analogy. In one important sense, Marxism is a religion. To the believer it presents, first, a system of ultimate ends that embody the meaning of life and are absolute standards by which to judge events and actions; and, secondly, a guide to those ends which implies a plan of salvation and the indication of the evil from which mankind, or a chosen section of mankind, is to be saved. We may specify still further: Marxist socialism also belongs to that subgroup which promises paradise on this side of the grave. I believe that a formulation of these characteristics by an hierologist would give opportunities for classification and comment which might possibly lead much deeper into the sociological essence of Marxism than anything a mere economist can say.  Joseph A.Schumpeter.
Quoted from Daniel Chirot and Clark McCauley in Better Angels: "Marxist eschatology actually mimicked Christian doctrine. In the beginning, there was a perfect world with no private property, no classes, no exploitation, and no alienation—the Garden of Eden. Then came sin, the discovery of private property, and the creation of exploiters. Humanity was cast from the Garden to suffer inequality and want. Humans then experimented with a series of modes of production, from the slave, to the feudal, to the capitalist mode, always seeking the solution and not finding it. Finally there came a true prophet with a message of salvation, Karl Marx, who preached the truth of Science. He promised redemption but was not heeded, except by his close disciples who carried the truth forward. Eventually, however, the proletariat, the carriers of the true faith, will be converted by the religious elect, the leaders of the party, and join to create a more perfect world. A final, terrible revolution will wipe out capitalism, alienation, exploitation, and inequality. After that, history will end because there will be perfection on earth, and the true believers will have been saved."

This is what “some” Marxists want you to swallow—a blue pill of sorts: that though well over 30 countries have been run by avowed Marxists (all have had outrageous human rights records, immense democide figures, poor economies and little actual democratic pluralism), that Marxism has not yet been tried anywhere in the world. And moreover, that poverty is not caused by isolation, lack of human capital, corrupt inefficient governments (plutocracies), trade barriers, etcetera, but rather that imperialism and greed are the root cause of human poverty, that, and a general ignorance of the huge and growing middle and working classes around the planet to understand incomprehensible socialist’s economic theory.
The Yiddish writers’ sustenance, in the USSR's scope,
Obtained Uncle Joe’s booster shot, in 1952, the year I was born.
Back then, the Cossacks lived in hungry hovels, without much hope:
They starved for fifty years, like skeletal livestock, on piffle of wheat and corn.

Three decades before that, all the Kulaks ate slugs;
As Lenin confessed to Russell, and the progressives, still scorn.
It is a case of, one thing after another: ‘reality is optional!’
Moscow’s law: “What can be swindled will be shorn”.

Sheep’s shepherd; twenty million in gulag, slaughter up the millions,
Collectivist’s dumbbells in billions; emasculated skin, outworn.
For all the human sacrifice, the dull red mass, earns only Soviet ridicule.
You are to depart in sad remembrance: ‘It is the night’s blackest forlorn’.

“Beat, beat and beat again!”
Father is dead and child is unborn.
Wife is in line at the prison gate waiting ever in silence,
Commissar asks her: “When does the moon see the morn?”

In bone china, obese Mao croons poems for his cutthroat, cultural ravens;
Heads of the dead roll in Cambodia, which the countryside adorn.
If liquidation is inflated from pedophile priests to Marxist existentialists,
Sepsis socialism spread the plague from Cuba to Vietnam on its long sojourn.

We forgot the sorrows of the farcical sixties; lies of slick professors;
Voluntary serfdom in infected universities no one will care to mourn.
Q and A is useless, a denied history of murderous, revolutionary terror,
The book of horror will not be read unless the tearful truth is sworn.

Five years in the camps destroy, a tenner, the death sentence.
Grubby, fat fingers the mighty tree from Marx’s acorn.
The forest petrified into crooked, arthritic wood.
Hearts freeze in Siberia; they wear sweaty rags stiff and torn.

Gangrene songs, Trotsky prose, Gorky poetry, all state rape.
Music of sorrowful violin, endless drumming, baby-grand wailing, gnawed, angry horn.
The rude, dissident slayer conducts the orchestra with historical necessity.
Gouged eyes—no ears; horrified brain sockets left to Chekist porn.
