“He neglects to mention that many of them are actually just retirees. According to Saez and Zucman, whose data Stewart uses, more than 40 percent of all wealth belonging to Americans between and 90th and 99th percentiles is held by the the elderly, meaning age 65 or older. This is what makes wealth data a tricky way to measure class below the very tiptop of the distribution. Stewart’s “9.9 percent” includes a lot of working professionals and business owners with gilded academic résumés, sure. But it also probably encompasses a lot of 75-year-old former accountants and nurses and guys with construction businesses who made a comfortable living decades ago, bought a house, and paid down the mortgage while saving for retirement. There’s no real way to tell a consistent story about who these people are, which makes it a bit hard to blame them for the death of opportunity in this country.”
