That model works well for professional services (eg. lawyers, accountants, consultants) because require very little capital. Everything from the office they work in, to the computers they type on can be leased. The same can't be said for hospitals, which cost hundreds of millions to build and equip. How are you going to raise all that capital from only the doctors? They're rich, but not that rich. Moreover, the payback on said investment is on the order of decades. A doctor late in their career has the most to invest, but they're also nearing retirement. What are you going to do with their shares? Sell them to newly graduated doctors who are hundreds of thousands in debt? Let them keep them, at which point they turn into quasi-investors?
