If you're a baby boomer, the question is simple but uncomfortable: are you "rich," or are you just average? The answer depends on how you stack up against your peers—and the numbers show there's a massive gap between the middle class and the elite. The 55–64 group includes younger boomers (61–64) but also Gen Xers in their mid-50s. So ask yourself:Are you a "rich" baby boomer with $3 million or more? Or are you just middle class, hovering around the median $400,000?
