The author might be missing the main reason people donate canned food.<p>It isn't just cash vs goods, they also want to feel like they have made a personal contribution. I loved eating canned corn as a kid, same thing for canned string beans (don't judge!).<p>I, and others like me, want to feel like they are doing that personal act. Be it donating kids clothing that has been out grown, or our favorite type of canned goods.<p>When I was in college and had very little money to spare, I still donated canned goods because I wanted to help out. If I had been given an envelop and a form to fill out my CC details or drop cash in, I likely would have done nothing. And I suspect many other people are the same way. And honestly, back then as a poor college kid, spur of the moment I could go into my pantry and grab a couple of cans I got on sale last week. It'd be harder to donate money that has to be spent on future needs, which are much less certain than needs that have already been met[1].<p>Charities, and all human organizations for that matter, have to work within the bounds of human psychology, and humans are rarely creatures of optimal habits.<p>[1] I wonder how much of canned goods is new purchases versus existing purchases? I personally have gone out and bought canned goods specifically for a food drive. If the majority of donated canned goods are from existing supplies, than the article's entire point is invalid.
