San Francisco has banned RealPage, a software company that computer-generates recommended rents for landlord clients in what some are calling a price-fixing scheme. It’s a step toward curbing rent-raising collusion between landlords.
And now they're part of a cartel, which is not only illegal in the US, but illegal in international law. (The oil crisis of the late 1970s was thanks to OPEC price fixing. We're still sore about it.)
"As soon as the land of any country has all become private property, the landlords love to reap where they never sowed, and demand a rent even for its natural produce."
Adam Smith is massively misquoted by libertarians and conservatives. He railed against landlords, corporations, and monopolies. He's the reason we have the phrase, "rent seeking behavior".
