Socialist terms are fine for those politically involved but you need more digestible info for the masses. Keep it very simple. “The Working Class” is sometimes even too much. You need to reframe the US vs THEM to be Rich vs everyone else.

Dont say poor either. People dont want to think of themselves as poor even if they are. A lot of poor Americans think theyre middle class or petite bougouise but they arent. So steal the language. The Billionaires are attacking the middle class! Instead of convincing them they are something different than what they think they are just use their language to reshape their perspective.
