Any "profitably" run PE company is being sold for parts and its wiring is being stripped. Good job being better than a charlatan startup. Your employer provides nothing of value to society.
This is just completely and laughably wrong. You have no idea how many companies are now owned by PE, and the vast majority of them are run as solid, sensible businesses for five years and then sold again. You have bought into some caricature of what the PE world means.
I wonder if it's also simply selection bias, they only see the failures, because the successes are invisible. I know some tradespeople who set up their own practices and sold it to PE, and the practices are running similarly as before.
