[80% of Americans have some form of debt.][1] The average total wealth for all Americans is actually positive. [It's a little over $300,000.][2] But that number is really the skewed one, as it's significantly shifted by the 0.1% of the Americans [which own 90% of America's wealth][3].

As for the median, I can't seem to find that statistic, but I would argue that it's actually a less accurate picture than the average.
