The US needs to do more of what Robert Reich ("Inequality for All"), Michael Moore ("Where to Invade Next?"), Bernie Sanders and Plato suggest: copy what works from elsewhere in the world (which others often copied from elsewhere including the US in the past), strengthen unions and get people more engaged in all levels of politics. (The US isn't a special snowflake, policy prescriptions can be tried and customized for commonwealth utility. But first, get money out of politics.)
"The price good men pay for indifference to public affairs is to be ruled by evil men." -Plato
