Industrial parks designed for workers

  Since we all spend a fair amount of time at work, why not design industrial parks with facilities for workers? Things that may not be affordable for a single company might be much more cost effective if shared by all the companies in the park. I am thinking of things like a gym, day care center, small park or first class cafeteria.
  One advantage to company owners would be to provide a place where workers could spend their lunch hour without worrying about taking too much time. Another advantage would be from the business contacts generated from casual meetings.
