And here's a graph of median house prices:

That is almost exactly an increase of 8X, compared to roughly 1.5X for personal income. Do you think an increase of 1.5X over forty years or so counts as "barely increased"?
Of course household income is higher because most households have two wage earners instead of one. But that's still around 3X to around 8X.
And the standard deviation for property prices has increased hugely.
This has nothing to do with supply and demand and everything to do with the difference between an unproductive rent seeking economy which sweats static assets - including the workforce - and a productive creative economy driven by innovation and invention.
For all the rhetoric, the current economy has a lot more of the former than the latter. And this is only good for a small number of incredibly rich individuals - at the expense (literally) of almost everyone else.
