A similar system may prove beneficial here, both to reduce the litter problem they present, as well as to reduce the irritation of carts left out randomly in parking lots, rolling into parked cars, blocking parking spaces, etc. In the context of our "poor" community, this idea will no doubt be dismissed as visionary, at best.
Businesses will bemoan the additional up-front costs this will impose on them, of course. But these carts do cost them something, probably not a trivial amount, to replace when they go astray. And we consumers end up eventually covering that overhead cost.
Moreover, it's not unthinkable that responsible business people might be persuaded they have an obligation to be part of the solution to a problem of which they are certainly a part.
