> But the main reason for its decline, paradoxically, was its strength. Glass retailers who play by the rules of the market live off the fact that their products break, so they can sell more. A glass that didn’t break was a threat to profits. I've heard this story repeated multiple times but I've never bought it. Unless there is a glass cartel, i.e. crony capitalism, I have a hard time believing that consumers wouldn't storm the gates for unbreakable glassware. If I were a bar owner, and I had near 100% restocking of my glassware annually (which I believe is in the ballpark of the actual number), I would be willing to bypass my supply chain and order these glasses directly from the manufacturer. I can't see how someone couldn't make a decent living off the addressable market of one time sales of this glassware. This doesn't seem like it is a true market dynamic - but I might be missing something.
