My idiot lib sister in law blabs about healthcare in the US all the time.Back a few years ago there was a statistic that roughly 150k Canadians had health insurance policies for AMERICAN diagnostic clinics. Just getting a diagnostic test could take months or a year in Canada. Free healthcare ain't so free after all.
It's even worse in the UK... if you call for an ambulance b/c you fell off a ladder and broke your leg, that is considered 'non-life threatening' and it may take up to 24 hours before one is sent. Simply insane.
