Every other American is in the bottom 10%, and 1 in ~7,500 are in the top 10%.
If I were a gambling man I wouldn't take those odds.
1 in 10 Americans are in the bottom 10%.
i.e., the bottom 50% of Americans population-wise own 10% of the overall wealth, while the top 7,500 people (0.002% population-wise) own 10% of the overall wealth.
That said, those numbers are actually overly optimistic. The wealth chart offered up by the federal reserve show the bottom 50% population-wise only own 2.5% of the wealth. Particularly alarming (though not surprising) is how much that share has shrunk in the last 20 years.

Still, a quick google search says Europe's bottom 50% own only 1.2% of the wealth there.
There is a huge gulf between the poorest 10% and the top 50%.
