The work they do is of low value because almost anybody can do it. Morally they may not deserve to be poor, but nobody is going to pay them a lot of money to perform that work.
That's not true. Burger flippers aren't low paid because it is easy, thry are low paid because the supply of people willing to do the work is too high. If other, better opportunities become available for a large number of those employees, wages will go up.
Look at Walmart, they aren't raising wages out of the goodness of their hearts, they need to raise wages to keep good employees. (and probably a little PR and politics too)
