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.
