Ruccio explains with hard economic evidence that capitalist operations result in most of the wealth produced by American workers has caused the American worker to become poorer and poorer while the "owners" become ever richer by exploiting cheaper labor worldwide. Wealth produced by workers ends up concentrated in the hands of a small segment of society.
...capitalism means that capitalists get to appropriate the surplus and do with it what they want. They get to decide when and where commodities will be produced, and therefore when and where jobs will or will not be created. If that means offshoring production or purchasing inputs from producers in other countries in order to boost profits, they’ll do so. And workers in the United States will either lose their jobs or be forced to accept lower wages and fewer benefits in order to “compete” with the production of commodities elsewhere.Thus an economy, which is a vital part of every society, ends up under capitalism serving the needs of only a tiny segment or class of each society while producing many undesirable effects such as unemployment, poverty, devastating wars, etc. for the vast majority of people.
