Yup...
I have always been an advocate of a two tier system...16 to 19...no minimum wage for 90 days...pay what the market will bear....
Depending on the local economic conditions and locations it will vary greatly...
That will put lots of kids to work and start learning the value of a labor dollar...
20 and up...indexed to local minimum wages for 90 days...
except I would make it 13 to 19. My son when 19 was worth two men and paid accordingly. Make them earn it.
