The government will NEVER institute such a minimum wage EVER. Even they think it would be a good idea, it would open up a pandora's box...every other worker group in the nation who could remotely relate their job to public safety would demand the same amount.
Paramedics, lifeguards, school crossing guards, bus drivers, janitors, jiffy-lube technicians, etc, etc
The only way pay will go up is due to market forces...which could be an indirect result of hire experience/certification standards.
