Yeah it's nostalgia. You've getting old OP 😉
I think it's generally easier to have a good quality of life now: houses are in better condition, less draughty, it's cheaper to decorate, furnish and carpet nicely, cars are much much better (cars broke down all the fucking time in the 70s and 80s), clothes are way cheaper compared to wages, sorting things out is easier. Eg you could easily spend a day paying bills in the 70s, just that and nothing more, or buying a train ticket or something.
That said although it seems easier to make choices now re spending I do end up feeling baffled with the way information is put out to us by corps and orgs and I'm sure that is on purpose. It's like we feel we know more but in fact it's just different kinds of obfuscations and reading everything all through is time consuming and often not particularly elucidating.
I guess in the end we always end up limited by ourselves. Eg I got really excited about kazaa back in the day - imagine! Listen to any music you want! I spent hours doing just that, downloading loads of tracks I hadn't heard in years, suddenly it was all there for me without having to wait for it to hit a radio playlist. I really thought it would open up a new world for me
Now ofc I have Spotify and can do the same, but legally, but actually all Spotify does it let me listen to music I listen to anyway, or music very close to it. I can do more of the same, but not anything different.
As the years go by I've found that the best way of really opening up to new ideas is through the same mediums I always used and that were always there - trying different radio stations, at different times, reading new literature, physically going to live theatre and music, especially if it's an invitation from someone I don't know so well. For all the charms and convenience of the digital world, it's the analogue world that gets me moving forward.
