Haha. I came up with Usians while living in Panama. I agree with you, and United-Statians is better than Usian. It's America from Canada to Argentina, yet we claim the whole region. Ugh.
You have asked a question that I repeatedly ask myself. I wouldn't know the extent of what I know now, but I grew up middle class until my parents divorced.
Changing class status teaches you a few things. I questioned the shit narrative we're spoon fed and distrusted US intentions, but I doubt I would have looked further into US foreign policy.
However, there are many United-Statians who know the truth yet never left. Unfortunately, there are more that believe in the "saving the world" narrative.
I prefer living with you than in this fabricated hell. Your culture is authentic, intelligent, curious, and warm. Our culture is capitalism.
