Agree completely. Proof abounds internationally that a properly run government universal health service is more efficient, more effective and more ethical.
And you actually believe that the US government is capable of running anything in a more efficient, more effective and more ethical manner? Americans don't trust it because we are looking at the disasters they have created in areas such as the VA where we do have socialized healthcare and most of the 85% of us who do have health insurance much prefer not to let them run the rest of the healthcare system.
If I were to do a do over, I'd recommend fixing the healthcare system by focusing on the needs of the 15% uninsured. That 15% basically splits into 2 subgroups of insurance needs: the reasonably healthy group who needs insurance to protect them from major health disasters such as car accidents, cancer etc, the type of things that bankrupt people and the chronically ill group who have heart conditions, diabetes etc etc that lead to a steady stream of ongoing significant medical expenses year in and year out. For the latter group I'd propose something along the lines of the high risk pool in Oregon that namelessfly mentioned. For the former, cheap, affordable catastrophic insurance that protects against major health disasters and only major health disasters. And leaving the 85% alone! Yes I know there is a lot of room for improvement there but there is also a lot of room to make things worse and given the complete lack of competence they've exhibited to date. I don't trust the government to improve it.
