The Iron Law of Wages

thank you, I was going to guess that but i get confused with just a one blank answer thinking the answer should only be one word

The concept you are referring to is known as the "Iron Law of Wages." The Iron Law of Wages proposed by economist David Ricardo suggests that in a competitive labor market, wages tend to settle at the minimum level necessary for workers' subsistence and survival. The idea behind this law is that as population grows, the supply of labor increases, which puts downward pressure on wages. Consequently, workers' wages would only rise to a level that could cover basic necessities, preventing starvation, but not much more. This theory is often associated with the Malthusian theory of population, which Ricardo built upon.
