Americans have so far put up with inequality because they felt they could change their status. They didn't mind others being rich as long as they had a path to move up as well. The American Dream is all about social mobility in a sense - the idea that anyone can make it.
There's something fundamentally wrong with a system where there's been 17 years of a Tory Government and the people of Scotland have voted Socialist for 17 years. That hardly seems democratic.
