Housing needs to be decommodified. It needs to stop being a retirement plan. We need to stop letting people hoard it. We need to stop subsidizing exurbs and making it illegal to build the kind of walkable communities people actually like. Case in point: Red Vienna [1].
As another commenter noted, this is in every industry. Utilities are a particularly bad one including telcos. All the best ISPs in the US are municipally owned. Chattanooga was the first really big poster child for this.
Privatization of all these things is just rent-seeking behavior.
So many of society's problems come down to housing being too expensive. Anything that makes it expensive needs to be stamped out and that includes RealPage as well as Airbnb/VRBO.
This is a predictable outcome of commerce due to the limited supply of land and is described in some detail by Adam Smith and developed by later thinkers like Riccardo and George (who took it to its logical conclusion and inspired the board game Monopoly).
During the 20th century, economics was wholesale rewritten to blur the lines between land and capital so as to bury this awkward conversation.
The general recommendation of these early economists was taxing land - moderate in the case of Smith, up to 100% per George. This amounts to public ownership of part of the profits of land ownership.
No, it is not. Communism tried that and all communist countries failed spectacularly. Public ownership in practice means that everyone has rights but zero responsibilities.
Taking people's private property is not a solution to any crisis. This whole housing thing looks like "I want to have my cake and eat it too".
