Not a Trump voter, but this is a huge area where many Democrats are flat wrong. Talking to some Democrats about the supply problem with housing is like talking to some Republicans about why a hard line abortion ban makes maternal mortality go up. It can’t possibly be true because the ideology says it can’t be true.
Here is an article [0] that talks about the issue. This is a real problem driven by this collusion, don't act like it isn't. And now that Trump is in office, these kinds of investigations are going to disappear and the housing crisis is going to get worse.
I think the argument above is that democrats are one of the drivers of building restrictions, leading to the ability to collude. If new entrants to the market were plentiful then the existing cartels would be undercut. Also, rent control puts a tight lock on the rental market by forcing landlords to keep their rents high lest they become locked into the low rents they may otherwise offer.
I'll leave it as an exercise for the reader whether to be on board with that assessment, but there is a reasonable argument to be made that a free-er market could actually benefit housing costs.
Where do LLMs come into this?
