I'm sure many company heads start hyperventilating when considering products that last 50 years. What will they sell after everybody has one as is satisfied?
It sounds like a stupid problem, that quality might ruin the economy, but I'm sure we must be looking wrongly at it somehow.
For example, if things last, you need buy much less, that's good for the individual's economy. And if that then is bad for companies' or countries' economy, they have based their income on false idols.
