I am skeptical of any "top X wealthiest" lists especially for an analysis like this which claims that people are no longer getting rich through inherited wealth. Inequality has gone up a lot since the 1980s and to me a smart person who inherits wealth is not going to flaunt it and probably not going to want to be in any kind of Forbes list. There are plenty of ways to move wealth off of your personal ledger while keeping it in the family, ways that don't even count as "hiding" and I just know casually as a peasant who will never encounter a single one: foundations, generation-skipping trusts, CLATs (maybe the "charity" is your foundation!).
