Totally wrong strawman missing the bigger point. It's still a vague, misguided utopian ideology focused on helping the rich supposedly "overproduce" while doing nothing for everyone else. That's trickle-down economics 101.
Supply and demand is not an ideology, it’s the most fundamental way that pricing works in a capitalist society. Has been studied for centuries. To think that supply and demand would not apply to housing and instead be trickle down economics is a hell of a statement.
Well, you have the economics wrong, and our ability to handwave at each other about whose policy is "miguided" and "utopian" seems like a pretty boring conversation. Regardless: it's obviously not "trickle-down economics". Trickle-down economics are policies that deliberately and directly subsidize the wealthy in the hopes of spurring demand.
