Actually having that same argument with people I know personally, IRL. I disagree, at least with respect to the UK (I can quite believe it works differently in the US, which is so different in so many ways, not least because of the vastly lower population density overall and the fact that it isn't dominated by one major city where all the jobs are and most of the wealth is).
The issue of housing shortages is far more complicated than that. I mean, where I am there have been new multi-story blocks of flats go up on almost every side of me in the last few years (pretty much every bit of unused land is getting built on now), but housing remains horribly expensive.
Which seems consistent with the argument in this opinion piece.
The ‘yes in my back yard’ voices are getting louder, but housebuilding quality is more important than quantity, says writer and curator Phineas Harper

I don't believe Starmer is right about housing, and it seems part of his horribly misjudged faith in 'deregulation' in general as the recipe for 'growth' (the favourite idea of those who want to pretend to help the poor while being terrified of annoying the rich), which seems very badly timed given we've only just had the results of the Grenfell inquiry (that catastrophe owed a huge amount to decades of right-wing fixation on 'removing red tape').
I do have mixed feelings about the Green Belt. I've always thought it existed largely to preserve the pretty views and fresh air of the wealthier people who mostly live in it or next to it....and can see it as a kind of ligature strangling the city...but on the other hand, once I eventually managed to venture out there (after a childhood spent pretty much entirely in inner London) I had to admit some of it is quite nice and there's something to be said for being able to actually get to some greenery occasionally. The main problem though is not the lack of housing as the lack of _affordable_ housing, especially in the places were there are actually jobs available. There are places where housing if fairly cheap, it's just that there are no jobs in those places.
