Reasonably, wealthy people don't see poor housing as an option, though there is gentrification.

I see you're versed in the left-NIMBY lingo. No, 'trickle down economics' was an excuse for the wealthy to pay lower taxes. When fancy new housing is built, the property taxes are higher.

> Making expensive cars wouldn't seem to result in many more affordable ones.

I think you're intentionally missing the point. The price came down when more cars could be manufactured.
