> Society has become significantly wealthier, despite the absurdities of inflation and interest rates.
That is the issue with the absurdities of inflation and interest rates - how do you tell whether we're better off if the yardstick for measuring value is being purpose fully distorted? And the way we measure the distortion seems to be unreliable;I don't see how inflation is supposed to rise faster than wages but asset prices seem to be inflating substantially faster than the inflation rate making it harder to save. GDP also disassociated from energy use in the 1970s so I don't see why it going up means I'm better off either - I need cheap energy to be comfortable. All the stuff GDP measures is nice, but rising energy prices are a massive problem that we don't focus on as much as we did when they were driving GDP growth despite the fact that they are still a major part of existing.
Asia is better off in real terms. A friend of mine was talking about how he went home to his ancestral village and they had toilets now which is a massive QoL step change. So if "society" is global, yes.
If we're talking English speaking countries, you can tell me I'm better off, but I'm not sure what metrics you're using or why we believe they matter. I have access to much better electronic equipment than my parents, and our ability to cure ailments has improved markedly. But a bunch of people I know had to leave the city because they literally couldn't afford to live here. Debt seems to be out of control. We're seeing political discontent in the UK and US that seems to be linked to people who don't believe that they are becoming better off, and I tend to believe people when they say that.
TLDR; maybe. But you're making a claim that is vaguer than you might think. We're a much smarter society than we were 50 years ago, but it is less obvious who it is that is "significantly wealthier" and what that means.
