Dr. Thomas Sowell can answer your question much better than I. He often rihts about this seeming paradox.

Suffice to say that rent controls and the implementation of zoning land for greenbelts (which discourages development of housing of all kinds) in many southern California cities means that you have an entrenched gentry (not surprisingly, aging liberals who pay low rents and put the rules in place) that forces out low-income wage earners. Land is snapped up (the houses on it are worthless by comparison) by the wealthy, who know there is no other land to be had.

The seeming paradox in my work is that I have a clue about spelling, but insist on ignoring it.
