They've had a career of treating patients. I think they've satisfied the moral imperative already. And selling to PE doesn't necessarily equate to "profit maximization". It could just mean "decent sale". As the OP said, often there simply isn't anyone available to buy it out at the timeline it needs to be bought out.
> The solution I'd want to see for situations like this is to find a way to sell to the people who have a continuing interest in how the business is run: employees and customers. The "exit" that does right by all interested parties would be something like having a newly formed employee coop gradually buy out the founder's ownership stake.
I don't doubt that this can work (it has for other businesses!). However, a given doctor wants to retire soon. Can you point him to a concrete plan to set this up? As in a firm that will have said plan ready, does all the legal work, and manages the terms with the existing employees/customers? The doctor already has his hands full treating patients and running the business.
If you cannot point him to such a resource, then do you see why he'd just sell to PE?
