My family (father, brother, and I) worked for Uris Brothers/Uris Buildings Corp. out of NYC. We built two office towers in Philadelphia, years ago: 1 and 2 Penn Center. Uris was an "Investment (read: owner) Builder", the world's largest, and there was no draw to return to that city to build buildings. Methinks politics of that city had something to do with the reluctance. We did build, as half-owners, the Washington (DC) Hilton, but returned to our roots in NYC. Washington (local) politics was a bear!
As far as strikes by public employees go, they should be totally outlawed. Fire the bums! Ronald Reagan did that with the Air Traffic Controllers, with admirable results! If cops, firemen, transit workers, teachers, nurses, etc., don't like it, they can walk. We can all cheer and say "Bye-bye"!
