What do you mean "Society has become significantly wealthier"? When I think of wealth I think of an individual's assets to liabilities. If we look at the total value of an individual's assets with respect to the labor it can purchase, I don't think society has gotten all that wealthier. Maybe you're conflating quality of life with wealth?

Better quality and more abundant goods with decreasing marginalized labor costs is what we should expect since technology is naturally deflationary. If anything, the oddity is that food prices ever increase over time when quality is stagnant. The book "The Price of Tomorrow" does a good job giving a perspective on this.

There's also the problem of misguided/fraudulent capital investment which is when governments and corporations raise costs under the guise of technological improvements. This is when they say they add in extra processes for quality when they're really just lining their pockets. Think medical schools and doctors (https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6288618/), the FDA processes(https://en.wikipedia.org/wiki/Criticism_of_the_Food_and_Drug...), etc.
