I am interested in what tools wealthy families use to plan their financial future for several generations ahead. For example, to ensure stability for children, grandchildren, and even great-grandchildren, as well as to create an asset management system that will work for decades.

One solution could be to create a Family Foundation. The family's capital is transferred to the foundation, where it is invested and generates income. This income can then be used to support family members, educational programs, or other purposes, allowing family capital to be preserved and grown over many years.
