Desiring a better work/life balance (really, what it means is less work, and more 'life') is nothing unique to medicine, nor is it a new issue, nor does it mean that anything is technically 'wrong' with the way it currently is. You could survey almost any field and find similar results. "Excuse me sir, would you prefer working more, or spending more time doing other stuff?"
We physicians in general work longer hours than the average 40 hour week. We knew this (hopefully) going in to the gig. The work load is tremendous, but it is what it is. We must tread very lightly on what we deem to be a good solution to this issue.
