Just speculation but I would guess most laborers and even material companies aren't from the city let alone county. Trickle down economics has not proven to be a good idea Imho.

Or they have more than enough money for both.

If they weren't tax exempt, the Pittsburgh region is still widely known for healthcare, and thus a lucrative place to operate. They would still have good reason to take the same action. But even if they didn't, they aren't the only corporation on the block. In fact, their tax free status is setting an example to other corporations like Google and Amazon, which then go elsewhere when we don't give them tax breaks.

You are correct that their developments add economic value to the region. But so does a for profit development, and they don’t get tax exempt status.

I agree with you here, that there are taxes being paid with this money, but the government is a hungry pig and even with those taxes being paid through permits, payroll, sales tax, etc eventually the property is no longer generating income to the government and they're going to get it from somewhere else. Building these structures raises the property value of the surrounding area, so is almost like a cruel joke to everyone around them; they come in and put their building there, don't pay any property taxes but everyone else has to pay more when their property is reassessed.

I love when people talk actual sense and get downvoted because reddit is a cesspoll of useless people.
