First of all, communism isn't utopian. Even communists don't think it will be some paradise where all worries disappear. You'll still have to fight racism, sexism, bad weather, famines, etc.

But it's often better for an average person from a country of a starting equal level of economic development. You've got to give it the "If I was reincarnated in a random person's body, where would I want to be?" test. US is a good answer, but it's got a way higher level of economic development with a big headstart. Even then, you could end up in the hood and die early and stressed. When you give the test comparing countries of equal starting economic development, it becomes a lot more muddled.

Like, would you rather randomly live in Cuba, or Somalia? The place where you get free education, health care, etc or a place that is also extremely poor but you don't get that stuff? You could reincarnate as some rich, warlord there, but would you want to take that chance when you could reincarnate in Cuba as literally anyone and not be worried about ending up homeless? When giving realistic comparisons like this with proper historical context, and you do it over and over again, they tend to come out on top.
