Teachers in California earned $78,711, on average, for the 2016-2017 school year. While that’s over $18,000 more than the national average for a teacher ($59,850), it’s still not enough to buy a home in the most expensive housing market in the US.

In some states where the average teacher salary is lower -West Virginia, Oklahoma, and Kentucky – public school teachers have gone on strike to protest low pay, and to fight for more benefits and education funding.

San Francisco was actually one of the few cities where housing became more accessible for teachers, but the prospect of a teacher buying a house by the Bay is still abysmally low.
