the market is not correctly assigning value to new housing, but inflating it due to artificially generated scarcity, which has become systemic due to a failure by government to intervene (specifically by deregulating and privatizing the immigration system). this is generally what happens when governments fail to correctly intervene in markets and instead allow them operate without regulation, they fail to assign value correctly.
we consequently are not facing a failure in government oversight, but a failure in a lack of government. we're facing a market failure.
this market failure requires government to intervene by directly building housing itself in order to increase supply to lower costs to increase demand.
the cause of this overwhelming market failure is multiple governments at multiple levels "leaving it up to the market" rather than intervening and fixing it. the market will not fix itself; it hasn't fixed itself yet. a hands off approach will simply lead to more market failure and continued impossible housing costs.
both major party candidates, however, are true believers in the religion of markets. their faith will not be shaken no matter what evidence is placed in front of them and we have no expectation in front of us as voters and citizens besides another four years of market failure and another government that refuses to intervene to fix the broken market.
