Americans reaping what they sow. What do you expect? The US is one of the most capitalist societies on earth. American propaganda over more than a century has built a culture which venerates the super wealthy and teaches deep hatred for the poor.
This worked to keep a small but important middle strata of workers in line but access to that class is harder and harder. If the system starts to fail for the majority of people, of course people are going to be angry! And American propaganda prevents little class solidarity or basic awareness of the exploitative system, so Americans channel that anger into hatred for one another.
