It used to be remarkable to drive a car 100k miles without major repairs. Volvo dealerships in the 80's and 90's would give you a badge at 100k milestones to advertise how reliable their cars were compared to others.
Anything tech related is just light years ahead of what it used to be, and for far cheaper. 65"+ OLED TVs for less than a couple grand are pretty much science fiction come to life. Gaming consoles are super-computers compared to an NES.
For many appliances, if you pay an inflation-adjusted cost for what a 1980's family would pay you can get something that will last forever. Last year I bought a commercial microwave for about $300 that has a single dial, hardly any features, and likely will last longer than the first microwave my family owned and also paid ~$300 for. Adjusting for inflation my new microwave is vastly better and cheaper than my childhood one.
I play guitar - in 1954 a new Stratocaster sold for $249, which is about $3k in today's dollars. And $249 today will get you a guitar that's easily as good as most 1954 Strats. If you spend the inflation-adjusted equivalent you're in ultra-luxury territory.
Want good furniture? That's ALWAYS been expensive, but you'd typically buy a table for the equivalent of $5k in today's dollars and expect it to last a lifetime. You can spend $5k on real wood furniture today, but nobody does.
Housing materials are much better and cheaper with the possible exception of copper pipes and anything made of real wood. Certainly builders of McMansions are cutting corners at every opportunity, but if you do your own building/finishing these days a lot of materials are available that will outlast their 1980's equivalent, and the cheap options are better.
I think a lot of this is a lack of perspective - everyone wants better things but nobody actually wants to pay for it.
