government cheese is a process cheese designed for long storage so it basically is white label velveeta. the real purpose of gov't cheese was to have an excuse to buy milk from failing farmers to keep the dairy industry from failing. it later turned into other campaigns like 'got milk?' and the stupid milk mustache ads. ironically, when the basedbean farmers needed help suddenly dairy was unhealthy and margarine was the new thing.it's also why things like eggs and coffee seem to flip flop between being healthy and unhealthy; the government isn't afraid to gerrymander stock prices to artificially change their values.
