Why havent they pulled the plug on the $400 Contractor license fee

Joe Reda introduced, and Chris Coons signed into law the contractor license fee. The county has spent more than $6,471,767.00 on creating and staffing this enterprise killing bill. There are now only 3600 (approximate) contractors paying the $400 license fee. This means that the county has lost at the very least $4.320,000 since implementing this bill.      That's  a  %150  loss on investment. How long will this go on before they will raise your taxes again to cover their loses?     If you get the chance ask them why?
