Revised version: Country A is an imperialist country, and Country B is a colonial country. Country A has the capacity to produce cars, while Country B does not. One worker in Country A produces one car in 5 hours, selling it locally for 50,000 yuan. After deducting 3,000 yuan for wages and raw materials, the capitalist’s free surplus is only 47,000 yuan. In the B market, because B cannot produce cars and demand exceeds supply, Country A sells the car at a price equivalent to 20,000 yuan based on 10 hours of local labor, but still only pays the local workers for 5 hours of work. The deduction for raw materials remains unchanged. As a result, the capitalists in Country A unilaterally appropriate 197,000 yuan. The extra 150,000 yuan is the surplus value extracted from B’s laborers by the comprador bourgeoisie of B, who buy the cars in B, which is the excess profit of Country A’s capitalists.
