The PERCEPTION is high. Many of the employed docs I talk to - its shocking how little they actually know about the business, yet maintain a high level of pessimism and perceived expertise of the business side.Maybe. But the perception of risk of fresh/recent grads is very high. Perhaps they are mistaken.
There still is the risk of being assimilated by the hospital, exploitive senior partners, the partnership that you are working towards being a "sub-partnership" that is not revealed until you put your time in, etc.
Something like a "sub partnership" would be revealed to you before you started. Same with "buy ins". None of that stuff will be a surprise.
Sometimes an AMC/Hospital/Employed gig makes more sense.
But I think what happens is impatience. "Im done waiting" and you take the bird in hand with the employed job vs investing in the right thing for the long-term. And then this decision is rationalized by the ideas you gave above.
