Philadelphia is one of the most corrupt places on the planet. Ask anyone who has done contracting work there.
My BIL.
He got a contract in south Philly to install an elevator onto a 3 story building with basement (4 floors). After he signed, the city came and mandated he pay all employees a minimum of $50.00/hr on said work. He about lost his butt on that job! Since his men were already getting between 30-35/hr. Major hit to the wallet.
