Late Stage Capitalism

If you're talking about communism in the USSR, people having "nothing to strive for" and being "depressed and drunk" were definitely not the primary issues. That's a seriously uninformed and sophomoric position, and you should read up on history a bit if you're curious. There were serious issues relating to central planning that were the cause of the famines, their military logistics issues, and corruption at the local level. Not to mention the various internal and external conflicts that plagued the USSR. These did not relate to some vague notion of people being unmotivated, depressed, or drunk.

Bonus historical fact: Russia's rampant alcoholism has roots in the Czarist period where the Czar decided who could distill and sell alcohol. At various points, this meant aristocrats only and then a state monopoly. During the czarist period, vodka sales to Russians made up like 20% of the state's income - so the czarist state had a vested interest in maintaining the demand for vodka. During the communist period, the government tried to ban or limit vodka production and consumption numerous times (decreased worker productivity, made people bad parents, etc) - but that went about as well as prohibition has gone in other parts of the world.
