As someone living in Canada, let me respond to these.
Waitlist: Many are on wait lists, for sure. Those wait lists qeue people by need, not income, but it is true we could use more doctors and nurses!
Wait times have increased, I agree. More people = longer wait, as the population of doctors has not increased as much as the general population I guess.
Doctors moving to the US? Definitely. Same with writers, designers, athletes, etc. Those that move to the US strictly for professional medical reasons? Maybe all of them, maybe less. Didn't see a stat on that.
* Maybe ask people who have full coverage affordable health care if they would switch to a private run system?
I know some of the less wealthy would prefer an imperfect, universal system to no coverage at all.
