I'm as pro capitalism as it comes but private equity should not be allowed to operate in the consumer housing market. They can develop and sell houses but cannot hold is my point of view.
Another market where PE is incompatible with human life is healthcare. It becomes a race to maximize profit at the expense of worse patient outcomes and worse healthcare availability for all. They close redundant, less profitable hospitals (usually rural). Same with pharma: they jack the prices on common meds and only develop profitable ones, not effective ones or needed ones.
