Totally agree with you; this frustration is a direct and obvious result of decades of policy failures. I just worry that a lot of the ensuing anger is a bit misplaced.
I do think that there's been a sharp acceleration in recent years towards actual concrete steps, even though they're not super flashy and will take more time to see results. There's been real progress towards zoning reform, abolishing parking minimums, and other bits of red tape that have played a huge role in housing costs exploding.
