While Richmond Computer is in the tech business, every now and then we do projects such as network wiring installation which isn't terribly complicated.
However in the city of Philadelphia, to do so, one must be a union member and pay exorbitant fees to the Licensing and Inspections department to run low voltage wiring. On top of that, a city inspector has to sign off on drawings, then inspect the work when complete. This only adds to the cost of doing business in the city, and no one but the unions and city wins. Not a problem in the suburbs.
