Now the union has forced Sanders to capitulate on wages and health care. But why stop there? The Sanders union seems to be suffering from a lack of imagination. If union organizers really want to hold Sanders to his own standards, then a $15 minimum wage and premium-free health care should be only the beginning.

Sanders has promised to cover the cost of prescription drugs and make sure “no one in America pays over $200 a year for the medicine they need.” He has promised to pay for “universal child care and pre-kindergarten.” He has promised free college, because “you are not truly free when the vast majority of good-paying jobs require a degree that requires taking out tens or hundreds of thousands of dollars of debt to obtain.”

He has promised to “free generations of Americans from the outrageous burden of student loans by canceling all existing student debt.” Is he setting an example by providing all these benefits to workers on his campaign?

Of course not. Because if he did, his campaign would quickly run out of cash.
