Obama, a community organizer by background, used some public money for what you mentioned as
economic stimulus when he took power after the great recession. He would have done much
more but we all know about the obstructionist congress of course. Would you say that
Obama was simply trying to do what you mentioned?

I can't speak for Obama's intentions. Economic systems are controlled by national legislation. Corporations are legal conceits. In Europe, corporate boards must contain 'stake-holders' which must include workers and community. U.S. corporate law is the Wild West of global finance, a land where the Supreme Court recognizes 'corporate personage' (corporations have human rights as individuals) and claims that 'money is speech'. The U.S. congress works directly for the elites as employees of the uniquely U.S. 'democratic system' of campaign finance, K street lobbying, and revolving door patronage. Elite income has grown uninterrupted for 50 years. It works.

Unless U.S. citizens become a direct threat to this process, it will not change. Read: violence.
