The United States is in a pain crisis. The use of pain killers increased by 50% from 2006 to 2012 and one recent estimate put the cost of physical pain on the U.S. economy at $635 billion — a 1,000% increase from 20 years earlier. At the same time, a widening income gap, growing sense of financial desperation, and erosion of the middle class have elevated economic insecurity to the top of the political agenda in the United States.
