John Maynard Keynes and Karl Marx would agree most about the answer to which question?
O A. Should governments take total control over economies?
B. Are precious metals a good measure of economic strength?
O C. Do free market economies create problems for workers?
D. Is it right for strong countries to control weaker colonies?

Option C: Do free market economies create problems for workers?

Step-by-step explanation:

There was a law called Say's law which states that capitalist production generates its own markets, and therefore, there can't possibly be any gluts or overproduction of goods in relation to market demand.

Now, keynes and marx rejected this say's law because they both believed that gluts or overproduction may likely occur.

They believed that this law would make capitalists own nothing but the right to sell their labor in exchange for wages.

That due to the capitalists competition with themselves for profits, it would squeeze as much work as possible out of the working class people at the lowest possible price and that this competition would cause some capitalist firms to fail, and thereby increasing unemployment among the working class.

Thus, it's clear this was an answer to the question on whether free market economies create problems for workers.
