Then do tell me why companies like Amazon and Walmart get away with, essentially, state subsidies for their employees and why in many parts of the US teachers complain about being massively underfunded, to the point of Oklahoma switching to 4-day school days so teachers can work on the side to earn money?!
As for Oklahoma, that's the voters making the decision that cutting school hours is a better choice than to increase teacher spending. Sure you and I don't agree with this choice, but elections say Oklahoma voters do.
This is why making companies pay tax penalties if their workers are on food stamps is a terrible ides. It'd make employers more wary of recipients of welfare, thus making it even harder for poorer minorities, single mothers, etc. to find jobs. And not to mention, it'd create further incentive to outsource or automate these jobs.
