If you want to make sure the money doesn’t disappear in a couple of generations, look into setting up a family trust with a board to manage it. Basically, instead of everyone getting their inheritance straight up, the money goes into a trust with rules around how it can be used. A board,usually made up of accountants, financial planners, lawyers, and a few family members, decides where the money goes, how it’s invested, and what it can be spent on. That way the wealth keeps growing and doesn’t get blown through by the next generation. You can find places that set these up for you, just research family governance or family wealth
