I have several issues with this article.

One, 175% of market rate vouchers?! So the homeless are living better than non-homeless stable working families who are actually able to take care of themselves? In what world is that just?

Two, why do they classify gentrification as a problem? Would they rather have a uniform distribution of crime and poverty across the city? Because if so, the rich people will move somewhere else, and the poverty problem will only snowball from there, bringing the general quality of life in the city down.
