It sounds like housing is getting bigger and more expensive but wages haven't grown enough to compensate for this. The postwar US population would have still retained its place as having the world's richest middle class if wages grew with the level of productivity and wealth that was generated since the 50s.
One of the big reasons housing is so expensive now is because it's meant to be, under this current economic system ( yes, I'm talking about free market capitalism). Homes built back in the day have now appreciated great value for those who bought cheap decades or even years ago. Most people want a decently big house and there is high demand for living in the top metro areas of the country ( because of the greater economic opportunities and 🞵🞵🞵🞵 to do).
Yeah, one could go to a small town out of the way in the interior ( and many people do, if they can work from home and want a less crowded environment), but that's not and shouldn't be something people have to do, especially if they already have economic/social ties to an area. Not to mention how expensive moving is.
You have a lot of housing being built in this country but most of it is pretty much luxury development most folks can't even afford without going paycheck to paycheck on rent or mortgage.
There has to be some balance. That balance will require that those who are benefiting greatly from this current system give out concessions that will help the rest of society. The rich folks can only stay rich because most of society works for them and buys their 🞵🞵🞵🞵. The rich folks can always leave to go to a place that's a tax haven, but then they won't be rich for long. Regular folks will have a easier time transitioning back to a more communal economy in which we don't need to eat Monsanto GMO foods and deal with 🞵🞵🞵🞵🞵🞵 corporations.
