Housing is so outrageously expensive in San Francisco the city can't hire enough teachers

The Business Insider reports:

Housing in San Francisco is expensive.

So expensive, in fact, the city's schools can't hire enough teachers because the cost of living is so onerous.

According to a report from KTVU in San Francisco, the city's school district needs to find 51 more teachers in the 2 weeks before school starts, but is having trouble hiring due to the high cost of living.

Thank you rent control ! Thank you zoning ! Thank you land use restrictions ! You've destroyed affordable housing in San Francisco. Why not try a free market in housing , with real property rights?
