Do these loons truly think businesses would willingly stay and fork over THAT kind of money for entry-level workers barely qualified to ask ‘do you want fries with that’? Attempts to artificially raise the minimum wage does nothing but hasten the development of the automation that will put many of these same unskilled workers out of work or bankrupt the businesses that would have otherwise hired them.
And/or create wage-push inflation which ripples up the wage ladder (unions love it since many of their contracts are keyed to the minimum wage), and then through the rest of the economy. Nobody wins for long.
