To your first point: people don't typically start out that way, things spiral down. And it's much harder to get out of that spiral if homes are completely unaffordable. It also doesn't help that the most temperate places (where you won't die of exposure if unsheltered) are also the least affordable places (because they're prosperous and haven't built nearly enough housing).

> Also most "affordable" housing initiatives attack it by mandating "affordable" for new construction instead of just letting developers build what they can make the most money building. No developer wants to build "affordable" homes if they can build and sell high-end homes. So by imposing "affordability" mandates, they just encourage developers to go elsewhere.

> New high-end homes make the older homes more affordable. New "affordable" homes simply don't get built, at least not in anywhere near the numbers that are needed.

Complete agreement that the current approach is not working, yes. The right approach is to build, and keep building, until everything is affordable. And the political challenge is the existing cohort of people who think a house should be an asset that appreciates rather than a necessity of life that everyone should be able to afford. People who are put in a particularly bad position by that (e.g. difficulty moving or retiring because housing prices went down) may need help.
