The headline is bogus. Trump is saying that he would bring back jobs that are worth &15 per hour, not raise the current minimum wage. Hamburger flipping is not a job worth that, are are not intended to be lifelong career choices.
They say everyone reaches their own level of incompetence, the rate of paying being what the employer is willing to pay for the task to be done.
The number of times a headline is erroneous these days is disgusting.
