The United States is very diverse. I don’t think it’s possible to describe what living in America is really like. It’s too broad a question.
There really are some places with white picket fences, lovely homes, warm sunshine, children playing on the sidewalks, etc.
There are some places where people don’t know their neighbors, put bars on their windows, and fear violent crime when they walk outside (or when they walk into their homes, although that is not limited to people of lower socio-economic status).
There are too many people who just don’t have a home at all.
There are people who have to drive to see a neighbor, and those who hear their neighbor sneeze through the wall.
There are people who chose which BMW to drive on a daily basis, and those who hope to have enough change to catch a bus.
Some people have a private doctor basically at their beck and call, and those who wait for ten hours at a free clinic for penicillin
Some children attend schools with small class size, an abundance of books, lots of extra-curricular activities, .and caring, knowledgeable teachers. Many children waste away in underfunded schools.
Most people are in the middle somewhere.
In my experience as an American, I think it’s the best design I’ve encountered. It has flaws, for sure. There is too much violence, too many conservatives pushing their agendas on others, not enough support for social causes. However, I am free to do as I please within reason. With education, which can be attained by anyone through hard work and the right connections, the world is open to me. Americans are able to change their station in life for better or worse, we’re free to choose our cities and places of employment (and I was about to say who we marry, although that’s not true) and what we do for entertainment. The police are generally trustworthy, and I usually feel quite safe.
