The point is, Amazon, Walmart or any other company with massive number of employees is gaming the system. You are right, eventually we will run out of money, the WE being the middle class. Any business that has a certain percentage of revenues drawn from tax based welfare, employees or not, is in essence drawing money from taxpayers. I'm all for helping out the poor, especially those that are working and making an effort, but the middle class has been disproportionately paying for it. Not only are we primarily paying for the welfare but also increasing these huge corporations bottom line. I would like to see any company that takes in a certain percentage of SNAP or other welfare based programs be subjected to a baseline minimum living wage that is higher than normal federal minimum wage (federal minimum wage currently is pathetic considering the amount of wealth in this country IMO), knocking them out of welfare state. That way the burden is shared and lessens the load on middle class since they are taking a percentage of my taxes for NON-PUBLIC use. Big, rich companies will always find a way to game system but if no one points out the lack of fairness, they will never change. I am speculating Bernie is simply trying to find an alternate way to market a higher minimum living wage at federal level. If they could find another job it will more than likely be the same scenario and they will still be taking our tax dollars.
Flat/Fair tax would be a great start to help avoid large corporations from gaming system IMO as well, but that's another topic...
