The top 250 million adult Americans are richer than the top 250 million adults in Europe, Asia, Latin America, or Africa. So what are you talking about?
The median American is far richer - with a far higher income and disposable income - than the median in Europe, Asia, Latin America or Africa. It's not remotely close in fact.
The median in Europe for example, pegs you down toward an income of just $12,000 and a net worth of only a few thousand dollars.
The US is a country of 330 million people where the median person is wealthier than Germany or Sweden. The US is by a considerable margin the wealthiest per capita large population in world history.
I'm pretty sure this is due to some really poor surveys, not the actual state of things. There's a number of debunkings, too. [0]
> America might have the greatest level wealth inequality in the world.
According to Wikipedia, the gini wealth coefficient list (as of 2000) goes Namibia, Zimbabwe, Denmark, the world as a whole, Switzerland, and then the US. [1] Most people would not consider Denmark to be a particularly unequal country. For more recent numbers it seems that Russia, India, Thailand, Indonesia, Brazil and China all have a higher proportion of wealth in the hands of the 1% than the US does. [2] That's as of 2016, and I don't think the US was able to 'catch up' that much in the past 3 years.

Just look at garages. They are often so packed full of junk there is no room to park a car (and then end up filling driveways and the street bumper to bumper). Once you start paying attention to this you notice it a lot.

About 3% of the US workforce seems way high not to be including a bunch of stuff one wouldn't expect.
