When you do that, you see something interesting. There are three things, the "three devils" as I heard one article call them, that are largely responsible for the perceived decline vs 20-30 years ago: the cost of housing, health care, and college tuition. Of those housing is the worst because it's the most universally unavoidable.
Ignore housing, health care, and college tuition, and think about it...
Individual wealth: vastly higher, especially if you include technological growth and what's possible today and what you can buy today for the same $$$.
Buying power: similar in many areas, slightly lower in energy but made up for by vast efficiency increases (e.g. I drive an EV that costs less than $10 to charge in my garage), slightly lower for groceries but a lot of that is self-inflicted. Vote, people.
Job availability: mixed, and very much depends on whether you compare to a recession period or a boom period.
Overall health: mixed.
