@jb having studied this closely (i am making facts up in real time), the long waits are more about insufficient surgeons and tests/imaging that require high-dollar equipment
both of these are fixable
the cheapest healthcare is preventative, i.e. don't get fat, keep your bloodwork up to date to spot problems earlier, etc.
the most expensive healthcare is defensive, i.e. "we're going to run a million tests so i don't get sued into oblivion"
provide for the first, keep the second down to a dull roar, and you've saved a hojillion dollars
but people tend to get caught up in extreme edge cases, which as a programmer i can appreciate, but come on, let's grab that 80/20 low hanging fruit you goobers
