As other have said, housing, at least in the US, has always been seen as an investment, and investments are supposed to appreciate in value. It is difficult to sell to political bases that one of two things must then be true: 1) People who bought houses 20+ years ago will have to lose equity on the house which they potentially were relying on for some amount of retirement, or 2) The government will have to step in and fill the gap (a la systems similar to agricultural subsidies). Neither of those things would you be able to sell to a wide enough base that they could be acted on.
In the end, this was caused by two things. On a practical level, prices continued climbing while wages stagnated over the past 40 years. On a more philosophical level, I personally don’t think that necessities such as housing should be commodified.
This also brings up the fact that single family homes, the predominant home type in the US, are not good from an environmental standpoint or an urban planning standpoint. It would be better to convert into duplexes and such. In the end, I agree that buying a home is way too much, but in the long run it may be good that the market is pushing more people towards lower impact forms of housing
