No argument here, I totally agree that the politicians are by far the main problem. I don't want to go off-topic but look at Mid-Market, you could argue that the primary reason it's been a "dead zone" for so long is that supes like Chris Daly and his ilk mercilessly blocked any attempt at gentrification there for years.
And what has been a major driver in the recent renaissance of that area? Daly finally got termed out, the Mayor and Board turned a bit more business-friendly and decided to throw companies a bone (for once) by offering the Payroll Tax break and voila, Twitter moves in almost immediately and we're off to the races!
