In developed countries, labor is universally expensive, while goods are cheap. In places where labor is more expensive, the cost of living for the wealthy is high, but low for the poor, making it easier to get rich; because the poor can do many things themselves and also work for others. The poor have no other resources to utilize, their only usable resource is labor—this is human-centered. In underdeveloped countries, labor is universally cheap, while goods are expensive. The cost of living for the wealthy is low, but high for the poor, making it easier to fall into poverty; because the only resource the poor can utilize is labor, while material resources are already monopolized by the wealthy. The higher the prices, the easier it is to exploit the poor—this is material-centered.
