You can disagree if you wish, but it is a fact that when a low level worker goes from $10/hr to $15, the plumber you hire will now want more. So will any skilled worker, and if their businesses don't increase their pay, they will go to one that does. Because of increases in wages, prices also increase, so that $15/hr will end up buying the same amount of goods as the former $10/hr. And as a side benefit (?) some small businesses who can't make ends meet will close, thus eliminating a few more of those $15/hr jobs. Note that McDonalds is already eliminating some humans and replacing them with machines. Other businesses that can afford to do so will do the same. As I said, the only entity who actually benefits is the government.
