Morris Fishbein (JAMA editor and very influential medical administrator of the 30s and 40s) warned against employer provided coverage, and his warnings have proven true. Back then, a day is the hospital was $5, and it was more of an enticement to employment that actual significant benefits.
Providing healthcare to a population (or deciding to let it provide for itself) is probably one of the MOST complex social/governmental issues that has faced modern man. Anyone who claims to have all the answers, or even thinks its a single-faceted solution is crazy, or trying to push an agenda! One this is for sure....when there's this much money at stake, there WILL be corruption involved.
