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.
The Supply and Demand model makes some assumptions that are not always true (perfect competition, for example).
The model isn’t an ideology, it is just a model. But there are a lot of ideological beliefs around this stuff. Some people seem to think that all markets have perfect competition, or that the resulting efficient pricing is inherently always good.
Housing seems pretty far from perfect competition to me.
