quickly appreciating assets preferably purchased from other losers when they lose their asses and collect monthly rent too.

I wouldn't say quickly appreciating, though. It's a fairly slow growth rate for someone with that kind of money. They diversify into real estate because it creates some tax protections (your costs) and it's fairly stable. Like buying into a terrible small business, but one that magically won't fail. The things that could cause total loss to real estate are usually handled in standard insurance, unlike a business that can just tank.

The thing is, as you and the other person said, it's all about the big companies who own tons of real estate AND the big companies that manage rental properties.
