Personally, I think a public health insurance plan is not going to accomplish anything as long as patients still have to deal with no co-pays, deductibles, out-of-pocket expenses, limited provider networks, and lifetime benefits caps.
Another reason why medical conditions are a major contributor to personal bankruptcies is the loss of income, so even if your medical expenses are covered, unless you have managed to build an emergency fund, you are still in danger of losing everything.
What really annoys me about the healthcare debate is that everybody talks about what it's going to cost, but nobody seems to talk about how much money it is going to save; or the fact that healthy people will be able to work instead of staying home sick, which means increased tax revenue.
