I assume you know what the f in fica stands for. 75-90% of payroll tax, depending on your state, go to the fed. there is little to no direct local benefit from a company being in your city. corporate taxes, payroll taxes, all go to the fed. where the community benefits, and where local leaders place their bets, is that they will reap gains (more significant than the subsidies they gave up) in sales taxes (retail), gas taxes, property taxes, etc. the company might sponsor the local little team, or the pbs station (tax breaks, once again for the corporation) - indirect benefits like that.
what Alexandria argued, and is a legit concern, is what will happen to the people born and raised in these communities once the people making $150k/yr move in? it's called gentrification. where will the poor people go? what will the community look like 10 yrs from now? newer, shinier, a lot like every other suburb in America. sometimes the pros don't add up to the cons. contrary to conservative philosophy, it's not always about money. there is quality of life. there is the uniqueness of a community - the architecture, the culture, the history.
