The same pattern of hospital work process and crazy shifts occurs also in countries with very different healthcare funding where the vast majority doctors definitely never become rich and are significantly behind the other "highly skilled" careers.

"highly doubt anybody would put up with what you do for med school if you're prospects of earnings was similar to that of a business analyst." - I'm asserting that people do put up with that in many places around the world, where doctors' earnings actually are quite similar to that of a business analyst. And not because they're somehow different, homo sapiens think/work/behave pretty much the same everywhere. The only practical difference that comes to mind is that they don't go into immense debt during med school like in USA.
