Most people have a vague "the government tells you what to do in every aspect of life" sense of communism, and think socialism is like decaffeinated that.

If you come at it without using the words, and the audience is labor, you can usually get them on board. "If your boss doesn't even go into the office and makes seven figures off your work, and you make five, how does that feel?"

Of course, some people are so conservative they're happy to stay in their lower tier of the hierarchy.
