The USSR was a developing country, and generally lacked luxury commodities, and depending on era, had a mostly unaccountable Politburo and a lack of food in the early stages.
By metrics, the Russian Federation has relatively recently surpassed life expectancy of the USSR, and now has more open travel and access to western commodities like smartphones, but you’ll find many older people in Russia who wish the USSR never collapsed (the majority, in fact), though again that’s also partially due to nostalgia for being an important global power.
