It is untrue that some are poor because others are rich. If an order of society in which incomes were equal replaced the capitalist order, everyone would become poorer.
Ludwig von MisesThe Reichswirtschaftsministerium ('Reich Ministry of Economic Affairs') tells the shop managers what and how to produce, at what prices and from whom to buy, at what prices and to whom to sell. It assigns every worker to his job and fixes his wages. It decrees to whom and on what terms the capitalists must entrust their funds. Market exchange is merely a sham.
