Unfortunately deregulating them will do much the same. BlackRock promotes YIMBY because that will allow it to expand its rental property portfolio, effectively generating new cashflows from the poor and middle class to wealthy asset owners. In fact deregulation/regulation is a false choice. Cashflow should go in the opposite direction by raises taxing on the wealthy (including real estate investments) and building public housing.

I completely agree we need to tax the rich and build public housing, but we do also need to allow for greater density in metropolitan areas. We have to build more housing and if we aren't increasing density then we're creating sprawl.

Sprawl chews up more and more farmland and forest, lengthens commutes, increases congestion. There's enough subdivisions and single family neighborhoods already.
