Fire them all and rehire others simple. Want a $15 hr job go find one and get hired. Cant find one get training or go back to school and learn a good paying trade. Minimum wage is just that a stepping stone to the workforce not a life long career.
95% of these protestors have never worked for minimum wage and never will.
They are communist agitators, traveling from protest to protest, whether the protest is for increasing the minimum wage, against cops shooting black criminals, for rent control, against Exxon, for solar power, against white urban mayors, for gun control or against the G8.
This is the culture that spit out Barack Obama onto the national stage. They are "community organizers" tasked with getting the "community" to disrupt American society. A great day is when they can gin up a riot, burn down a few businesses and get the tear gas flying.
The stooges they've actually sold on the cause de jour will be the ones who get billyclubbed, the professionals will be back in their comfy corporate hotel room by that point.
