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.
