Thomas Sowell is always right on....
"The same politicians who have been talking about a need for "affordable housing" for years are now suddenly alarmed that home prices are falling. How can housing become more affordable unless prices fall?
The political meaning of "affordable housing" is housing that is made more affordable by politicians intervening to create government subsidies, rent control or other gimmicks for which politicians can take credit.
Affordable housing produced by market forces provides no benefit to politicians and has no attraction for them."
