people are not poor because they spend too much on groceries. There's already a non-trivial amount of effort spent on making groceries more affordable for those with limited budgets (e.g. food stamps, coupons, offers, etc). Were it simply a case of buying cheaper food then we would have already solved that problem. Rather; it is more complex and opportunity is a more significant factor. Regardless the article discusses many grocery issues that poorer people suffer such as more expensive supply (along with limited access to superior supplies), less choice, inability to buy in bulk as well as restrictions on cooking or being time-poor.
