Among the six reactions to the Supreme Court's decision on the Affordable Care Act you published, only Congressman Kevin McCarthy's was negative. He contends that “more than two years after its passage, health costs have gone up.” He cites no evidence for this claim, and indeed, the U.S. Census Bureau only has statistics through 2010 on this. KaiserEDU.org, however, states that the rate of growth in recent years has slowed.
President Bill Clinton attempted reform to slow the growth of costs but was blocked by Republicans in alliance with medical insurance companies and some segments of the health care industry.
President Barack Obama co-opted the medical insurance companies by promoting a reform that offered them millions of new customers. Much of the health care industry came around as well.
The individual mandate that drives contemporary conservatives crazy was initially the idea of the conservative Heritage Foundation, was promoted by Newt Gingrich and adopted in Massachusetts by then-Gov. Mitt Romney.
Republican hostility to health care reform is obviously just anti-Obama politics. That the reform is good for the people is clearly illustrated by the statements you published from the CEOs of Sierra Vista and French hospitals and the director of county Public Health.
