How many heirs fighting in courts all over the world does it take to redistribute a multi-billioniare's wealth through court fees, lawyer fees, accountants, penalties, etc until none of them are supreme-wealthy anymore? Just never work again wealthy.
Even if some of them don't really want it, they could still find lawyers to fight on contingency and let them drain the wealth. Then donate whatever they might eventually get, if anything.
For example, Anna Nicole and her late husband's son effectively fed lawyers for years and years. Michael Jackson's estate has been tied up in litigation for decades. And Mike had 3 kids, Anna one surviving kid.
With over a dozen and counting Leon kids, and a ton of potential other types of suits incoming from world-wide plantiffs, it'll be interesting to see how that estate eventually gets drained and dispersed.
