No, because once private insurance is eliminated, there will be nothing to go back to.
I still have a little hope.
Depending on how the government option is worded, it may be possible that a few companies can offer private insurance to cover: (1) faster treatment, (2) higher level care, and (3) care which has been denied by the death panel.
These companies could be the nucleus of a return to private care.
Otherwise, as a senior, I expect I will be paying cash for most of my treatment in Mexico. May even have to move there to get reasonable medical care.
