In 1990, when the Baby Boomers median age was 35, they owned 21% of the nation’s wealth. In 2008, when Generation Xers median age was 35, they owned 9% of the nation’s wealth. While Millennials median age will not hit 35 until 2023, their share of the nation’s wealth will have to triple from its existing paltry 3.2% to reach the level of the Generation Xers. This has political implications.
