… diapers, laundry detergent, etc. are stolen because they’re as good as currency. Anyone who lives in a poor area can tell you there is someone reselling these for a bit cheaper.

Baby formula as well. That's the reason it's typically locked up in stores, drug dealers will exchange formula for drugs.

According to this [0] page, the most commonly shoplifted items are "apparel followed by cosmetics, alcohol and electronics," so if true, then it's not primarily a matter of essential items. It goes on to say that "incidents peak during December," which I think would tend to imply that people were taking advantage of product placement during Christmas season as opposed to stocking up on food and staples for the winter. (Of course it's possible people in distress are stealing luxury goods to sell at a discount to then acquire necessities.)

Purely speculating but I think that to some extent advertising has been a victim of its own success in convincing people that their self-worth hinges upon their ability to consume goods and services. If you can afford it, buy. If you can't afford to buy, borrow. If you can't borrow, steal. Just don't be poor and get caught. (Being rich and getting caught usually isn't a problem.)
