Developed countries are uniformly characterized by expensive labor and low prices. The more expensive the labor, the higher the living costs for the wealthy and the lower for the poor, making it easier to get rich; because many poor people can do the work themselves and also help others, they have no other resources to utilize, the only resource they can leverage is labor, which is human-centered. Underdeveloped countries are uniformly characterized by cheap labor and high prices. The lower the living costs for the wealthy and the higher for the poor, the easier it is to fall into poverty; because the only resource the poor can utilize is labor, while material resources have long been monopolized by the rich, the higher the prices, the easier it is to exploit the poor, which is material-centered.
