Like others who strongly support a single-payer health care system, I have been highly critical of the Affordable Care Act (aka Obamacare), seeing it as a bureaucratic monstrosity that was designed to keep the useless and parasitic health insurance industry in business while also allowing the hospital and drug industries to keep making exorbitant amounts of money. I also felt that while it would help some people, it would not do enough and would not reduce costs much.
It turns out that I was likely wrong on the last point. I went to a talk at my university yesterday given by one of our professors J. B. Silvers, a national authority on health care policy and someone whose opinion I respect a lot, and he says that that given the constraints, he thinks it is going to work out pretty well, and that those who are currently uninsured for whatever reason will be able to purchase pretty good health insurance policies for less than what they currently pay. Others seem to agree.
There are still some kinks to be worked out but he is optimistic and now, so am I.
