According to modern economic theory, workers are not paid a share of the factories profits at all. Wages are paid according to supply and demand, capitalists are paid according to supply and demand; there is no ‘sharing’ going on. I find that even some economic literates have a hard time understanding this. They make arguments about why capitalists would deserve some of the profits, such as the time preference argument, but they are missing the obvious economic fact that workers are not paid a share of the profits at all. Capitalists bid for labor, that’s what determines wages, not the factories profits. Workers don’t produce a factories output, they only produce their labor. It’s reasonable to make some counterfactual arguments about who should get how much compared to whom, but suggesting that profits are actually shared between workers and capitalists would be a fundamental misunderstanding about the way a market economy works.
