The point is obvious. Once healthcare becomes a ward of the government, it is subject to all the usual political forces. Interest groups lobby to the advantage of their constituents. Decisions are eventually made based on political exigencies. Medical care is the plaything of every other November's crying need.
You will get the care you're given under ACA. It is sad to see a few hundred medically ignorant politicians in DC decide whats best for everyone. But, as the old saying goes, in a democracy you always get the government you deserve.
