link bait. "Super-rich" in the title when it was only 25M threshold for the article. 25M is hardly getting one into "rich" category. At 4% draw it is 1M/year, just 5-10 times a salaried employee level and even less than that if a family of 2 earners is considered.
yes, in 2004 the income was median - 44K/year, mean - 60K/year, which is only 25-16 times less than 1M/year (25M equivalent at 4% draw). 20 times more than average isn't "super-rich", it is even hardly just "rich"
