I don't want to be too hand-wavy, but this feels like such a "get off my lawn" type of comment that I can't even start to analyze it. So many of the items listed are 100% nostalgia or personal anecdotes generalized to a whole population.
Disagree with OP about induction cooktops; they are magical.
Low quality everything exists, and mass-market everything exists -- but niche interesting everything is cheaper and easier to get than ever.
I travel overseas often for work. Over the years, bringing gifts home for people has gotten much harder -- because the "good" versions of absolutely everything from everywhere are available at home for affordable prices already.
Finding something that isn't just a tourism-souvenir (like a shirt with the name of the place) keeps getting harder.
It’s perhaps more fun to find a “diamond in the rough” than an “already cut diamond in a jewel store”.

Cities are comparatively packed these days with higher end coffee shops and pubs/bars with extensive beer collections.
Not to mention you can get high quality beans shipped anywhere you want, so you're better off than before!
Yes, Starbucks sells burnt coffee — Don't go there! Go to the local coffeeshop that roasts their own beans. These exist in just about every city with a population of 100k or a college. I would say that coffee in general has become a lot better. At the high end not much has changed but the low end is much better than it was in the 90s and the average is still a lot better.
Beer — I can get some really good quasi-local beer in just about any grocery store in the country. Yes, lots of hoppy IPAs but there's always a lot more non-hoppy beers to choose from.
