"$530.8 million in tax breaks, 11000 jobs eliminated, "
I can't speak to your specific example as I have no details, but what I will ask is this: Without the tax breaks how many jobs would have been eliminated or never created that much sooner?
So... one of the reasons why allowing "freebies" or whatever to companies is a bad idea that was included previously mentioned (by you, I believe) was of the strain on infrastructure the state/city will endure. Lets look at a few things:
o 50,000 people either unemployed or under employed (many likely receiving some type of state aid)
o current PA highway/road maintenance budget for the entire state is 170 million per year (https://en.wikipedia.org/wiki/Pennsylvania_Department_of_Transportation)
o expected tax income from 50k employees for the state of PA would be about $1200 per (at about $40k per employee at PAs income tax rate) + sales tax (6%-8%). That's a pretty huge chunk of change. Over $6 million per year.
So. We have over 6 million per year coming in to the state via income tax and probably at least a quarter again as much in sales tax on a LOW-BALL average income of $40k per year per employee. That's less than .4% of the population of PA (which is about 12million) providing about 3% of the entire transportation budget. I'm pretty sure that cancels out any concern about that. And that's not even including the increased sales tax.
Also, it would be difficult if not impossible to determine how much the state will no longer need to spend on assistance to who knows how many of these 50,000 possible newly hired folks -- but that just adds to the net gain to the state.
