This is a long video (42 minutes) by Professor Jeffrey David Sachs in which he argues that the present extreme polarization in America is rapidly approaching a breaking point. He argues that the worsening wealth inequality and the people's near-total lack of trust or confidence in the system is unsustainable. It's an excellent speech IMO. Those interested in American politics should give it a watch.

Only two things are infinite, the universe and human stupidity, and I'm not sure about the former.
