Because that was a time before commerce, before money, debt, etc. A time when every human was starving. Then, someone invented money, and people could acquire goods that they desired to consume without waiting for a double coincidence of wants. So that they could save in case of disaster. Someone invented debt, so that people could borrow money to create, or to survive until they could produce. Yes, now, we have to work for food, or we starve. Yet, before, we just starved. The market has led to the greatest increase of human well-being in history. Today I can, at any time (at least in a first world country), use pieces of paper to get food, nearly on demand, for almost no working time. At US minimum wage, 15 minutes can buy a fast food meal on demand. That's amazing. It's novel, its miraculous. We have an obesity epidemic in the US, something that would be unthinkable and impossible at any other time. And the places that are really poor? Like actual, crippling poverty? T(Hint, it doesn't exist in the US) those are the places without large state-sponsored capitalist markets. They are poor, not through any fault, but because humans are naturally poor and suffering. It is only through the market, and science, that this natural state has been alleviated.
