The danger of a socialist populist political movement to 'correct the social injustice' under those circumstances seems real enough, but how far in that direction can things go;
how can increasingly poor people be customers for the factory-owners products? Isn't it in the capitalists interest to have customers able to buy what's being produced?
Or are we tipping over into a 'tragedy of the commons' scenario with no one able to stop the destruction?
Is what's happening in the world economically the same thing happening in much of Africa physically: the exploitation of the weak by the strong?
The name of the game is standard of living, not cash
If lots of people are poor, then it's really cheap to hire the army of gophers, servants, and assistants that really determines the lifestyle of the rich. Also, the elimination of the middle-class means that there will be no source of competition for the upper-class, so they relax. Imagine being a wealthy person in 1980 and having a chunk of your fortune invested in IBM, while unknown to you people like Bill Gates, Steve Jobs, and Mike Dell were tinkering in their garages.

Normal people prefer to live in socialist Sweden than in San Salvador.
