You can complain about corporate welfare but only complaining about one corporation isn't really fair. Walmart utilizes local police forces to skimp on internal security (not too mention using welfare to subsidize poor pay), Military companies relying on politicians literally stuffing their coffers while the Pentagon argues otherwise, resource extraction companies are given free permits to bleed the land dry, agricultural subsidies, 0% interest loans dictated through the Fed, the auto bailouts, the financial bailouts, propping up home prices through artificial means. The pattern seems to be taking tax dollars and giving them to corporations.
