Question special

I appreciate being invited to participate in this forum. I have a question for the residents who are looking for jobs, which is how important is the opportunity to be a partner, or shareholder in the practice that hires you?
In the traditional private practice model, a new physician was hired, and after a few years bought into the practice. When it was time to retire, the remaining partners would buy the retiring partner's equity back. The advantage to this was that not only did one have a source of income from the practice of medicine, they also had an investment in the practice that would grow and help fund retirement. In addition. the "partner" would have a say in how the practice was run.
In an era when employment is emerging as the model of choice and (it seems to me) "lifetime" commitments to a specific practice are diminishing, how attractive is the option to become a part-owner of the practice where they work?
