So I work in commercial real estate, obviously a large private equity influenced industry. I've worked in REPE and in other capacities.
There's degrees of PE. Some good, fine, and some worse.
Take real estate development. It's probably one of the suckiest businesses to be in. I know 3 developers who have committed suicide because when things go wrong, your entire life collapses (you put up all your assets in order to obtain construction loans). The litigation, brain damage, and risks are enormous. Increasingly, the payoff is awful (due to worsening legislation and NIMBYism and worse market condiditions)
However, private equity in development I think is a good thing. When there are investors willing to put this money at risk, we get much needed construction of housing (see Austin, TX where rents are falling off a cliff due to over building).
Now look at Los Angeles, which new permits are literally almost non-existent because LA is one of the most hostile places for developers. You can't make money in LA, so there's no capital available.
Then you end up with "affordable" housing developers adding the only supply at $600-900k/unit costs vs the market rate developer at $300-600k/unit.

On the other hand, "value add" private equity is much more suspicious. It's more cut throat, easier to end up in crony capitalist situations by operating with a "cut expenses, provide less, make big bucks" model. The people in this world are the kind of guys who have never done anything hard with their hands other than gotten a sore thumb from pounding too hard on their keyboards to adjust their excel model ("Mr. The Model is Always Right") too hard all night long.
This is how we end up with old properties who get flipped 4x each being sold with "upside the seller was too stupid to take advantage of" and ending up in situations where tenants get priced out due to private equity seeking infinite growing returns. Oh and by the way, every previous owner did "lipstick on the pig" jobs because why not try to save costs and make your levered IRR 16% instead of 12%? You cannot show that kind of return when you promised 18%... then it'll make it harder to fundraise your next deal!
This isn't to say that "value add" is a dirty business. We certainly need to balance the incentive to modernize and renovate properties. An d developers overbuilding isn't always a good thing.
So its nuanced. I think people need to fairly give credit that there are both good and bad. The capital efficiency is real and produces real world outcomes since there is a strong financial incentive at the end of the door.
But financial incentives sometimes bump up to issues causing harm in real life, which need to be recognized and called out.
