You have a warped view of USA that doesn't reflect reality. You're seeing it through the lens of sensationalist news media and hyperventilating social media posts.

The actual reality for Americans is that it's a vast, beautiful land with an amazing spectrum of various experience. Violent crime is rare overall, and most Americans have never seen or heard any gun violence in person. Health care is available to pretty much everyone, even if you don't have money. We have state-run healthcare facilities that the poor can make use of like county health departments.

My life in the USA is great, because I don't live in a big city. I live on my own land, in a nice house that I own, and I'm just middle class income level. It's pretty easy to accomplish if you choose a low cost of living area rather than a big metropolis or suburb thereof.
