This. In Australia, half of the doctors do a 6 year undergraduate degree in medicine straight out of highschool while half do it as a 4 year postgraduate degree. Those that do the postgraduate degree don't need a PhD level GPA (they just need to do well in a test). Residency is not some sort of hazing ritual. Everyone is much happier, and it fixes the supply vs demand problem.
