I agree with your sentiment. I will, in all honesty, work till I am 65 mostly out of the desire to work. You have to be a gluten for punishment to even think about becoming an MD. However, that does not mean being a physician will exclude me from working part time. When there is demand for workforce and you cant fill the positions employers tend to play ball. Just a quick search on job boards results in this

"In fact, more physicians than ever are choosing part-timework. In Washington state, a recent study of primary care physicians showed that close to one in three practiced part-time."
Not many professional jobs let you turn off completely. Being engrossed in a project, deadline, case, or patient comes with the turf.
But Physicians bear partial responsibility of stigmatizing part time work. Especially per Diem work. what is wrong with them? what are they hiding? they must be incompetent! They probably cant hold down a job!
But even working full time I think the flexibility that is becoming the new norm may lead to interesting ways to balance work and life. Its nice to think of pie in the sky things sometimes, becoming an MD was a pie in the sky dream as well, and I just completed my first interview. I understand that I will have no life for the next 15 years. But the joke is on the establishment since I dont have a life right now.
