Searched for 2 or 3 years for a can-opener that wouldn't fall apart in a few months, finally found one. Nice big crank handle... but plastic knob on it. I don't think this can be solved by shopping at some hoity-toity NYC department store if only because anyone shopping at those places probably doesn't eat out of cans much.
Also, many of the foods one could have bought in glass jars just 10 or 15 years ago are now exclusively plastic. We switched to some regional off-brand on mayonnaise a few years ago because it was still in a glass jar, but even they eventually started selling it in plastic. Same with all the other condiments. Produce used to be in the egg-carton cardboard... I remember strawberries being sold that way as a kid. Or in little cheaply-woven baskets of some sort. I haven't seen that stuff since the 1980s. Deli meats used to be wrapped in butcher's paper, but sometime in the 1990s was put into plastic bags. Ice cream wasn't always sold in cardboard tubs (I remember even as a kid that the cheapest stuff was in plastic and I'm not sure why that is), but now even the premium brans have some plastic in contact with the product.
