It's such a complex problem, it's going to take a long time to fix. Part of the problem is people don't really understand what the real problem is. They think the problem is that there aren't enough detached, single family homes being built. I get why people would focus on single family homes because that's what Americans want. The "American Dream" is to own your own home in the suburbs, and if you think that everyone who wants a single family home should be able to buy one, then, yeah, you're going to see the problem as one of not enough single family homes being built. However, I would argue that the American dream itself is the problem.

Suburbs are expensive, and inefficient, bad for the environment, and bad for our physical and mental health. Suburbs necessitate car dependence, and cars themselves require a lot of expensive infrastructure. I know a lot of Americans don't like to hear it, but we really do need to be living in higher density urban areas. Higher density, mixed use urban areas allow people to walk and bike more, which is better for our health. It's also less expensive. The farther apart everything is, the more you'll need to drive, and that means owning your own car, which is expensive.

I don't think people even necessarily know why they want a single family home. I think Americans want single family homes because we're told from day one that is what we should want. It's our culture. You grow up, get married, buy a home in the suburbs, and start a family. You own at least two cars, you drive everywhere, that's the American dream. I think we need to start questioning if this is really what's best, and if we should really want it. I know I have, and I've decided it isn't best. I think I would be happier and healthier living in a mixed use urban area, where I could walk or bike to a lot of places, or take public transportation, and if I needed to drive somewhere, maybe I'd take a taxi or rent a car or use some car sharing service.

Very few places like these exist in the US, and that's because too many people still want to live in a single family home in the suburbs, and many of those people, also have most of their personal wealth in their home, so they push for restrictive zoning laws and other regulations, limiting how much higher density housing and mixed development can be built, thus making such areas relatively rare and thus expensive. There's a battle going on between people who want single family homes and people who want higher density, mixed use areas.

I know people don't want to talk about that, because they don't want to make it an us vs them thing, but it just is. Our desires are mutually exclusive, due to the finite nature of land. A given piece of land cannot be both a low density, single family suburb and a higher density, mixed use area, simultaneously. It must be one or the other. How we "fix" the housing crisis depends on which we choose to prioritize. We either find ways to build more and more suburbs, or we eliminate single family zoning and invest in building many more, higher density, mixed use urban areas. I know which one I choose.
