I think this is a fundamental problem with the UHC debate.
First, you are right about SS being a failed mess. But I think it is incorrect to compare it to UHC. They are two completely different concepts. Yes, they are both forms of social insurance, but SS is more of a retirement fund and UHC is more of a traditional insurance program. For example, anyone can borrow against their 401k, but CANNOT borrow against their car insurance. See my point? If we are going to draw comparisons, I'd think it would be more appropriate to use Medicare when considering UHC. And then ask: How does this program work at solving the problem? Is it successful or not? Do people like the program?
Secondly, there seems to be a misconception that UHC is the same as a socialized or a nationalized healthcare industry. It is not. Hospitals, doctors, nurses, EMT, etc. are NOT under the ownership nor employment of the government under the discussed UHC plans. There are currently 42-million uninsured Americans. UHC is a Medicare-type program with the notion of providing social healthcare insurance to these uninsured. If the private sector could pull it off, I'd think they would have already insured this massive market. But, they can't or won't. Bleh....
