Step back and look at what it fundamentally is.
Person A has a business they want to sell.
Person B has a pile of money and thinks that that business is (or can be) a good investment.
That's it.
So, what happens if person A is prohibited from selling their business? Are they forced to keep working because they don't have enough other savings to retire on? Do they shut the business down in order to retire? Something else?

Calls to ban private equity are attempts to play "shoot the messenger".
