I'm suspicious of govt-run healthcare. Look at Canada - their system is in collapse.
There are some very powerful, vested interests, namely the insurance and drug companies, that do not want public healthcare.
I am completely suspicious of private, for profit healthcare.
Are you seriously telling me that private healthcare is better? (Okay, private healthcare is better for the maybe the top 1% who can pay for their healthcare out of pocket, but if that is not you, the public system is better.) If I change employer, and therefore insurance policy and/or provider, I will never have to think about previous conditions that may not be covered with my new employer, for instance.
