Obamacare is the convenient whipping boy for everything that's wrong with the American health care system. Before Obamacare, the price of healthcare was skyrocketing. Its passage slowed the increase. Has Obamacare forced the drug manufactures to raise prices by enormous amounts? No. Has Obamacare forced employers to push ever more cost to employees? No. These things happened because our health care system, largely still in the hands of private companies, is totally broken. Not every insurer has pulled out of the exchanges. There are success stories where insurers  have strong networks and generally better understand providing healthcare for the sick as well as the healthy. The private insurers that pulled out had for years been cherry-picking members by denying anyone that has any health problems. They had never developed expertise that would even to allow them to correctly price their own Obamacare plans. The Medicare story is entirely different - now with record low cost growth.
