Yeah this is akin to saying our GDP growth is X% or inflation is 2% so everything is fine.

The measures for a quality of life I mentioned are something that every American or anyone in a first world country has to bear no matter what. Housing, healthcare, education. All of them have disproportionately gone up while the wage have stagnated. Average middle class family can’t afford to buy a house in most cities now, same with education without 22yr old kids taking on 150k loans. Or healthcare being the mess it is. But sure, everyone has a cheap smartphone and access to socials where they are busy fighting the culture war so everything is fine and dandy right?

While life expectancy going up is certainly not a bad thing, it can be hard to decipher what the quality of life is like in those later years. The life expectancy is going up because of drug/medical advancement, but obesity levels in the USA are at/near all time highs. Often times people are just moving surgery to surgery or drug to drug just to stay alive...

You clearly haven't looked at life expectancy in other places. Life expectancy in other places rose more than in the US. That's what's being discussed here.
