A very good argument can be easily made that a fiat currency is a necessary but not sufficient element in modern well-being.
Prior to fiat currencies there was a fixed amount of gold, and every coin in your pocket was a coin out of someone else's pocket.
Imagine a fixed number of software copies, a gold based currency is a lot like DRM for money.
Further more you can easily argue that making health care part of employer compensation (as is common in the US) leads to less well-being then making it a separate (in Europe often nationalized) good.
Those are two business issues with a direct impact on general well-being, and that's just off the top of my head.
