YES!  End Obamacare and dry up the already-shrinking government black holes that are "ACA exchanges."  A free and open insurance market and open, transparent pricing of medical services is all we need to fix our costs of medical care.  Doctors charge ONE price for every service, and customers compete for the lowest price.  Insurance companies charge ONE price- free of government strangulation and  regulation - and customers shop for the lowest price and best coverage.

Free markets, free of bloated government spending, free pricing structures, and free from government lies and corruption.  THAT is how we solve America's health cost crisis.
