The best way to refute Marxist logic.
The easiest way to refute Marxist logic.
Is to recognize a truth in plain sight that Marx denied due to his reliance on a poorly thought out "labor theory of value" he borrowed from Adam Smith.
The truth is this:
The world's first income, in money terms, was Profit income, not Wage income
This single truth blows up the entire edifice of Marx's "exploitation theory", which is assumed and taken for granted by every academic, intellectual, pundit, propagandist and believer of Marxism.
Contrary to profits being a deduction from what would allegedly have been formerly all wages, wages are in fact a deduction from what would have formerly been all profits.
Proof: In the "early and rude state of society", if there ever was such a time, economic activity consisted of no capitalist activity, there was no paying of wages or for capital goods, economic activity consisted of individual and family self sufficient producers who consumed a portion of what they produced and sold the rest for money.
The question that must be answered is, what is the type of income earned on the sale of GOODS?
It's not wage income. When a buyer buys an animal skin from a seller, the buyer is not purchasing that producer's labor, they are purchasing a good and paying a price for an animal skin. The buyer is demanding the good, not the producer's labor.
Here, because the seller incurred no costs of good sold nor wage labor costs, the money earned selling the animal skin is product sales revenues in money MINUS any costs of goods sold in money, which atarted as zero. So if the animal skin sold for 10 units of money, then the income earned by the seller is 10 units of money profit, for 10 minus 0 is 10.
Then, after real incomes grew to the point where producers could SAVE AND INVEST what they earned, they could hire labor. THAT is when capitaliam arose. THAT is when wage incomes started for the first time.
The income that was before 100% profit, now had associated money costs of production. So if the product sales revenues were again 10, and labor costs were 1, then profit went from 100% to 90%, because now the producers incurred money costs of production, in the form of hired labor.
Marx falsely reversed this reality of history and made the critical error that buyers of goods were not buying goods, but buying labor. This is how he was able to assert that profits are "deductions" of wages, and therefore assert capitalists are "exploitative" of laborers.
It is how Marx's followers to today shout slogans like "capitalism profits off the working class", and all those offshoots that also falsely presume wages precede profits.
