It would be very interesting to re-order the list by the amount of liquid wealth that each person owns, not including fake founder stock wealth that can't be e.g. theoretically sold overnight to avert a world disaster -- very different from someone with an actual pile of cash or bonds or gold.

Consider someone's effective wealth as the amount of liquid USD they could hypothetically produce in a 24 hour period by selling all of their assets, including market dynamics, and then tell me who the top 100 richest people are.
