It's true; here in San Francisco, the annual city budget is $11B, and each of the 11 members of the Board of Supervisors makes $110,000 a year (which sounds like a lot until you find out that thanks to our housing shortage, HUD defines the local "low-income" threshold as $117,400).
The 11 supervisors are the equivalent of senior executives. How much do you think a senior executive of a company with $11B revenue gets paid?
As a result, we get supervisors like Aaron Peskin (who's a landlord on the side and pushes civic policy that obstructs the creation of new apartments) or Chris Daly (basically a clown).
