For example, can the person of today afford a higher standard of living than one of 20 years ago - unclear, food has become disproportionately more expensive, housing cost has by far outpaced the wage growth, tech has become cheaper, but big-ticket items like cars are proportionally not cheaper.
From this, the person of today is poorer in tangible terms.
Did the infrastructure improve? - some, but I'd say it was a (sub)linear improvement in absolute terms - we certainly didn't build as much stuff as we did in the mid to late 20th century, and what we built before was the more important stuff, so the new stuff has marginal utility.
Did European industry and technology improve? I'd say in terms of relative importance, we regressed - there are huge gaps in European technological capability for which only foreign options exist - this didn't used to be the case.
Were there some big ticket innovations like Concorde or the Moon Landing or whatever - clearly no, the world seems to have lost its appetite for these kind of hugely ambitious projects.
This 'number go up' style capitalism is clearly not to the benefit of the individual, but I can't for the life of me think who does it actually benefit.
Forget 20 years ago, you can just back 6 years is enough. Ask any person when life was more affordable and job security better, in 2019 or today and everyone will say 2019.
Graphs like GDP or the stock market going up, mean jack shit to the average person when they can't afford a house anymore.
A lot of our economic growth was just on paper through financial instrumentation.
