First of all why ‘grandma’? My own siblings were born before the end of the USSR. It wasn’t that long ago.
Secondly you’re not gonna school communists on communism, I can tell you that much. The order to dissolve was illegal and protested against both in government and civil society. It required Yeltsin to proclaim the Russian federation, which he had no authority to do. The US spent millions around the world trying to bankrupt the USSR in conflicts and in their own society (eg the CIA art festival they wanted the USSR to hold in the 60s).
Thirdly the reason you’re working more than your parents were in the 80s and healthcare is so bad CEOs are getting merked is because there is no USSR. With it western governments were scared of the revolution coming to them and allowed us treats to placate us. I call them treats but I could certainly go for guaranteed raises and free healthcare.
Fourth Russia is kicking NATO in Ukraine so I’m not sure you’re doing much better all things considered.
Being born at the tail end of the Gorbachev years doesn’t make you an expert on socialism. Someone had to tell you eventually.
