NIMBY/YIMBY arguments seem just too convenient an excuse for me. It's almost if one has actively tried to find something that can plausibly explain the housing crisis but does not challenge the status quo of structural/systematic problems in any way shape or form. In Sweden the seemingly prime effect of these movements is to remove democratic influence to the benefit of construction companies, even though that only rarely is the cause of delays, and certainly not the root cause of the housing shortage.
And here's an anecdote from Sweden from the early 90s:
To get a cheap rental flat in high standard, albeit in a working class neighborhood, my parents were able to walk into the office of the municipal housing company and more or less pick a key from the wall and go take a look at it. If they liked, they got it. These were the days where the state still took an interests in providing housing to its citizens and planned, and built, accordingly. Now there's the market and a housing bubble consisting of too many expensive apartments that few can afford. To now suggest that the state should again start building cheap housing to a population where the middle-class is up to their neck in inflated mortgages is impossible. This is the real NIMBY.
