I would propose a $1.50 decrease in the minimum wage IF it was coupled with a pay for commute law. I would go down by $3 an hour if it also had a half pay for "on call" hours amendment.
The way I invision it is that everyone gets an assumed travel time (like 30 minutes or something) and if they are closer they get more free time, and if they are further, they don't get paid for the extra travel time.
