Physicians used to make nothing in training, just like nurses in training make nothing today. There's good reason for that- you're not a fully qualified physician in your field, and you're still learning and betting supervised and educated. Those nurses you work alongside are fully trained, can do their work with minimal oversight, and do not require an educational infrastructure to maintain.
I'm just thrilled it isn't like the old days where all physician interns were given was free lodging, a spend for clothing, and cafeteria food. I'm taking a huge pay cut for those training years, but something is better than nothing (our worse yet, paying to be trained, as happens in some dental GME).
