It takes about half an hour, if that, for Daddy Warbucks to flex his muscles and recoup his expenses for raising a minimum wage. Fire a few folks, raise a few prices and by lunch the accountants will be at a three martini blowjob lunch, celebrating their continued prosperity.
It takes much longer for the sucker at minimum wage to realize the raise made no difference in an ability to pay the bills.
A minimum wage is ineffective without a corresponding maximum wage.
Maximum wage! Start picketing for a maximum wage!
