1970s kid here.
OP - YABU about the 70s and 80s, but YANBU about the 90s.
70s - it still wasn't great to be a woman. They were mostly stay-at-home and housework was more difficult back then because the appliances were more basic. E.g. washing machine was twin-tub. Fridges were commonplace but freezers were a luxury. There were lots of power cuts. Rooms were divided up, so rooms were smaller, and fairly dimly lit compared to nowaday lighting. The toilet was often outside the house. Central heating wasn't that common yet. Sexism, racism and homophobia was rife. The main positive about the 70s though was 70s disco :-)
80s - a bit better, again with disco, music in general, and a great decade for movies. However, the fear of having a nuclear war was very real. This cast a shadow over most of the decade, and Chernobyl + aftermath only made it worse. Inflation was through the roof. Sexism/racism was still pretty bad.
90s - this is where I agree with the OP, that this decade was better than the 2010s-present. Music was at its best, especially Britpop/indie/dance. Politics started to ease off, especially with the voting in of Labour, and the IRA finally reached a peace agreement in the late 90s. It was a great time to be a clubber. Sexism/racism started to ease off a bit but still far from perfect.
00s - still pretty decent with early 00s music, internet and mobiles. Politics remained on the wayside, although 9/11 soured it somewhat.
10s and 20s - the rise of social media, and with that, the politics minefield. The left vs the right and Brexit. Corbyn destroying the Labour party so we're now a 1-party state. People getting into trouble on social media because of a witch-hunt digging up historic racist posts, but if it wasn't racist, they still get into trouble because someone got triggered. Then there is cancel culture for the same reasons. It's a minefield.
30s - probably a dystopian state and no one will have a voice any more.
