Good luck though when the person who learned how to be an assassin/shark and was able to build and maintain the wealth has handed it off to their kids (or grandkids) who probably never had much contact with them (what with all the assassin/sharkiness), and are now trying to judge well managed and safe from what they were exposed to as children. Which was probably massive wealth, and people who aren't always scamming you (because the filtering happened off screen).

Especially since you either have to pick someone (or a small group) from the set to judge, or have to deal with an ever increasing and ever more distant from the original wealthbuilding set of decision makers.

Definitely possible to do, but very, very, very unlikely and rare (based on clear examples around us).
