And that USSR never got to Communism, it was a socialist state with plan economy, that promised people that "one day we'll be able to move away from this imperfect system to some real cool utopian stuff, we just have to work hard for 20 more years". And it was 20 more years each year until USSR fell apart. So, nobody ever lived in a true communist state.

But placing it in America ruins the joke. The whole point is that it was absolutely nothing like that.

You won't be able to save people who are unable to draw parallels between a hypothetical and a real situation, even when they are given a dozen hints.
