Why do doctors own to work 36 hour shifts?

They might not be 36 hours, but I know they are reallllly long.Why do doctors own to work 36 hour shifts?
We work those kinds of hours as residents so we can return with the most experience in the shortest time. Even later we still have 4 years minimum for residency. It also help with keeping continuity of caution for our patients, but yeah, it sucks. Every once in a while we even achieve to sleep, too.
I'll be rich as Croesus after I get out of my $40k a year residency (if you average out the hours worked, we in actuality get smaller quantity than minimum wage), and then money back my $100k loans for med institution...so I'll finally have money when i'm 60. That'll be right when someone sues me for good their life.
Because they create more money than Jesus Christ and drive Porches.
being a doctor u r responsible of patients energy and health. So if greatly of patients need ur back then u can't say aloud no. This is a side of it the other side of it is gaining money.
