I don't think that Tupperware is downfall was that it lasted too long, because it doesn't I've had plenty of Tupperware pieces that I've gotten from my parents and grandparents that have failed and we're kind of broken when I got them. Additionally, there's always an ever-expanding market of people to buy new Tupperware I think one of their primary problems was their sales model of Tupperware parties. That may have worked well to bootstrap it but as the market changed they should have changed with it. The other problem is that Tupperware is lifetime warrantied so when you have a broken or failing piece of Tupperware you just get it replaced for free. Well that lifetime warranty is a great selling point it becomes a downside when you're replacing the product after 20 years. I very much like buy it for Life products but I don't expect some products to last or be warrantied literally forever. Many tool brands have been brought down buy the same thing. Especially ones that are geared toward home users instead of professional mechanics. If I have to replace a tupperware container every 20 or 30 years I think I've gotten my value out of it. Other brands also start to fail under this own weight of legacy. Because there are people who know and remember that certain brands have lifetime warranties and you can pick these things up at thrift stores for pennies on the dollar even when they're broken or damaged and get a brand new one.
