I work at the Navy Yard Corporate Center and my income tax from the City is more than the from the State of PA!
I wouldn't go anywhere near the City or spend a dime there if I didn't have to go there for work. They keep raising taxes and adding new ones then they wonder why they can't get businesses or people to stay in the City or even get anyone to shop there.
The Navy Yard Corporate Center is a special tax free zone for Corporations, but not employees. Once they finish building it up, they will repeal the tax incentives for the businesses and then wonder why when they eventually abandon the place.
Philly mentality is to incentivize to get businesses in to develop a spot and then tax them to death forcing them to abandon it and destroy the spot back right back into blight.
