Universal Healthcare goes beyond prevention. Everyone pushing for universal healthcare thinks of it as implementing healthcare at the level of private health insurance, but for everyone who can't pay. There are many expensive, niche treatments which universal healthcare would pay for which do not make fiscal sense.
I am for inexpensive preventative care, like free office visits, contraceptives, antibiotics, and setting a broken bone. I'm even for expensive care with greatly improved quality of life like hip replacements, etc. I am against the use of public funds for expensive 'treatments' with little success. Basically all of the sob-stories you hear about in the news, autism included (btw, the reason private insurance doesn't cover autism treatment unless the government mandates it is because those treatments don't work).
More expensive for who?
There's a case study about a Missouri town whose dominant business was lead mining. Despite dying from lead poisoning and their children growing up mentally retarded, the citizens were strongly against shutting down the refinery. "Don't take errr jerbs!"
How about we not destroy the environment we live in, to help the corrupt become wealthier. We're not competing with China in a race to the bottom.
