New York doesn't need that too.
If there isn't enough affordable housing for those lower-paid people, that's a failure by the local politicians. Don't blame the highly-paid professionals; they're not the ones controlling zoning and development.
Suddenly bringing in 25k high paid workers without a concrete plan on how to support that growth (including not giving gigantic tax breaks which would impact the necessary schools/police/transportation/etc of the area) is the root cause of the housing and traffic issues in Silicon Valley. I think local politicians are becoming a bit wiser to that kind of thing after seeing how gentrification is causing issues in other cities. NYC local politicians are probably the most aware, given NYC's history.
