I'm a little curious about this line from the article: "Here's the basic idea: 54.5% of U.S. consumers make less than $100,000 a year" According to wikipedia (http://en.wikipedia.org/wiki/Household_income_in_the_United_States http://en.wikipedia.org/wiki/Household_income_in_the_United_...), a household income of $100k would put someone in the 84th percentile. They put the 54th percentile at around $50k. Any idea what I'm misunderstanding here?
