I think you're missing some supply and demand calculations here. Since many people can't afford $5 for the milk, don't have a car, can't walk the 2 miles back & forth with 4 kids because they don't have enough stroller space for 2 and can't carry the purchased food and the kid at the same time, they just don't buy the milk. They buy the Coke for $0.99 at the gas station. If you're poor of course you want cheaper prices! "Let them eat cake..."
