That comes from buying companies, not owning companies. I think the stock market is the biggest problem, or for the housing situation companies buying a large number of houses is the biggest problem, or for medicine buying up patents to rack up prices is the problem, or for software buying up games/programs and filling them with spyware is the problem etc.

Builders typically aren't that evil, but builders sell to exploiters who are evil and exploit it as much as possible. You see this everywhere, that extra level of indirection where you aren't fine with exploiting people but you are fine selling your work to those who do exploit people. Exploiters are a tiny minority of people, but that is enough since they can buy up all the assets to exploit and thus become very wealthy.

Edit; And yes, those exploiters often have MBA degrees. Not everyone with such degrees of course, but the overlap seems pretty large.

You don’t understand, it can’t be MBA types because it’s just the natural progression of the world to become worse and worse. Obvious right? Now sit down and consume.

It's profit. Revenue minus expenses. Companies that optimize profit better than other companies are more successful. Emergent behaviour like evolution. Companies that don't optimize will not grow as much or even decline or disappear. It's self-selecting.

Planned obsolescence, private equity raiding, brand value extraction: these are steps to increase revenue.

Enshittification, corporate consolidation: these are steps to decrease expenses.
