It’s not just the value of the stocks that’s misleading, because not many owners get to sell the stock at maximum prices. It’s the tax that has to be paid to attain that value. A sensible statistic would factor that in.
I would like to know what, if any, portion of stocks and bonds is held in a retirement account. To me these accounts greatly inflate net worth, especially when the owner is not eligible to withdraw funds without penalty or retired and counting on withdrawals for support.
