Walmart has a large fraction of it's employees not making enough to live, and receiving food stamps to help support them, while at the same time Walmart is the single largest recipient of food stamps dollars.
They are double dipping, extracting wealth from a system that isn't supposed to make them wealthy. Food stamps is partially a government handout to businesses, but to agribusiness, not grocery chains, which did not need any government handouts and is only just now becoming an noncompetitive market.
Tax payers get to support "Super important job creators" by subsidizing their payroll, giving them constant tax breaks, and feeding a percentage of every single government welfare dollar into their private pockets.
