Construction is still mostly manual labor. Tech on that field has not kept up with progress of other fields. Add Baumols disease to the equation and you don't need "balance of power getting worse" to explain high house prices.

No matter the latter has lot higher productivity. https://en.wikipedia.org/wiki/Baumol's_cost_disease https://en.wikipedia.org/wiki/Baumol's_cost_disease
