"Horrors like that rich people only live in compounds surrounded by walls and armed guards, and the poor are dying because of no health care and no food, and the middle class does not exist."
The poor have essentially universal free healthcare in the US and have for a long time. I should know, I've used it before, and it's very easy to use. The poor also have the benefit of the one of the largest welfare states on earth, including the largest food and subsidized housing programs.
The US has the world's largest true middle class, with a median income among the highest of any country. A mere 1% of US labor earns the minimum wage, and the majority of those people are below the age of 25. The US also has a higher labor force participation rate than nearly all of Europe - while simultaneously having a high median income.
The US has a lower unemployment rate than: Sweden, Finland, Denmark, the Netherlands, Belgium, France, United Kingdom, Spain, Portugal, Greece.
And while Europe rolls around in a near depression, with Europe's GDP still at 2007 levels (since 2007 the US has added $3.5 trillion to its GDP) and high unemployment, US wages are expanding at the fastest pace in a decade, while unemployment keeps falling, which will drive even faster wage growth in the next few years.
