If you have a pension, you're an investor in PE. If you live in a country with a sovereign wealth fund, you're a beneficiary of PE. If you're connected to a school with an endowment, a lot of that money ends up in PE funds, and can fund lots of research and student resources.

So ya, I'd agree the PE is rarely good for anyone but the investors, but you'd be surprised how many people are investors without realizing it.

If all of those things never invested a cent in private equity funds that buy up existing companies to turn the screws on their customers and put the money into new business creation instead, they wouldn't be making any less money and the whole world would be better off, including the investors themselves in their role as customers and employees.
