It would increase labor costs across the board making automation to replace those humans more attractive. Automation is the largest blue-collar jobs killer in the country. No reason to put that on steroids.
So....you think automation wouldn't happen if labor costs were stagnant? That's happening right now with a $7.25 federal minimum wage. How much lower can it possibly get when you're already making hundreds of millions or billions? How will those wage increases have any effect at all on the bottomlineof the super wealthy?
