This is the unfortunate part about living here. It's a dog eat dog country. Every person for themselves. If the playing field was equal it would be a more fair system but it's not. It's obviously heavily tilted towards white men with money and the less white and poorer you are the further you get from being able to move through the class system and succeed. My wife and I work in tech and make really good money. My health insurance bills are very low, lower than someone that has to buy it through ACA which is a crime.

Living in America will open your eyes and show you a world that existed in the past for many parts of the world, especially in Europe.

The diversity thing is highly dependent on where you live. Here near Seattle, I can go to places where it's rare to hear english. I might hear Thai, Mandarin, Russian, Hindi and Somali all in the same grocery store. But then my kids went to a high school that is 98% white (it can get very white here in the Pacific Northwest). I grew up near Baltimore where my school was about 40% African Americans. My best friends until college were black. The diversity thing is highly dependent on location but people also self-select where and who they hang out with.

Finally, I will agree with you that many Americans are brainwashed to think the USA is the best country in the world (Trump feeds on this nostalgia). Usually, these are people that have not lived anywhere else (I lived in Thailand and Germany for several years each my father was in the diplomatic corp). I tell people we need to have some type of service for high school grads where they spend a year away working in another country or maybe in a completely different part of the USA to get a feel for a different culture. Once people see how well other people are treated in, say, France or Spain, they say WTF, why can't we get treated like this?

Knowledge is power and the wannabe fascists in this country know this. It's why they want to dismantle public education and the "elite" universities.
