What's the average earning capacity of a San Franciscan
Working class families earn up to $50000 per annum. Compare this with the $20,000 to $30,000 bracket that most other working class people in the US earn and you might believe that San Franciscans have it better.
However, San Franciscans are left with about the same amount of disposable income as the rest of the US because of the extremely high cost of housing and living in San Francisco. What's more, the value got from spending their money on entertainment was found be lesser than that got anywhere else in the United States, primarily because of the higher prices that were paid for them.
