High quality jobs improve the tax base, lessen the demands on social services

Except in this case, not only is Twitter asking to be relieved of $500K/yr in payroll tax burden, but also to get $250K in additional police presence in the area.

$250k in annual police presence is 2 more cops 24/7 and covers the entire proposed exemption district, which includes the Tenderloin - not just the street between Twitter's future front door and the subway entrance.

To put this in perspective, if 2000 Twitter employees purchase lunch near the office 5 days a week at an average price of $10, the sales tax revenue will offset the cost of the payroll tax holiday - not to mention the benefits of an extra $5m/year flowing through the neighborhood economy.

Well, I don't know that adding two more officers to the Tenderloin is the same as adding two more to Twitterland. I guess if Twitter is smart they'll have a Starbucks nearby or inside; I'm sure it'll work out in their favor one way or another. I certainly don't think Twitter is asking for the police presence out of concern for those living three blocks north, it would be fiducially irresponsible.

2000 lunchers to the tune of $100,000 spent in the neighborhood per week, are you saying that Twitter is not going to have their own on-site cafeteria?

He gave one example of how the numbers for 2000 Twitter jobs can scale to revenue. He hasn't done an analysis of Twitter employee eating habits; he's just injecting more numeracy into the discussion. On the other hand, a protracted argument about exactly how much lunch business Twitter employees will do is likely to harm the overall discussion more than it helps.

I see, more numeracy. Let me add: 40. Fantasy numbers don't help, and "maybe the city will even out in side-effects" isn't exactly moving the discussion along, either.

[tptacek]

Just for what it's worth:

* Fantasy numbers do help when they illustrate the scale of the dollar figures we're talking about. It is helpful to measure things in "Twitter employee lunches to break even". It's actually more helpful than "$250,000" is, even though the latter number is more "factual".

* If you don't believe it matters whether the city will even out in side-effects†, you're basically arguing there's no point to discussing incentive programs. All of them are cost-benefit investments (or gambles). Make the argument that they're bad gambles, sure. But it's probably not worth making the argument that the city shouldn't try incentives; you'd be howling into the wind, since every city in the country has, in the city council and at the ballot box, decided this already.

† And, tip, which I learned here the hard way: watch out for the double quotes; they can mean, "reader, this is what the person who I'm responding to just said; would you get a load of it?". You'd be surprised how irritating this can be to people. I re-learn this at least once every couple months.

I know those numbers sound high, but the number of high-quality jobs required to offset them are probably lower than you think, for two reasons (among many others): first, payroll tax incentives aside, Twitter employees still pay increased property taxes on average; second, low-income SF residents consume significant amounts of money in public assistance funds of varying forms.
