I've long felt that there needs to be a bill passed to charge companies $x additional tax each year where $x is the amount of government assistance their employees required in order to meet food/housing minimum standards. One way or the other, the companies that are making the rest of us pay for their employees to survive need to be funding these programs.
Or just increase minimum wage. 3x maybe?
Same thing, and simpler to do than making new law. I always prefer keeping tax simple!
