If you are looking for some guidance on this matter, then consider two intriguing articles by the same author. Each article reaches a different conclusion. The articles recently appeared in Forbes and are titled "Why Family Wealth Is A Curse" and "Why Family Wealth Is A Blessing." Interestingly, the author is a member of the family that founded the Georgia-Pacific Corporation.
Among the curses the author identifies are "too much too soon," "too much of a financial focus," and "ingratitude." In contrast, the author notes blessings that include "love," "choices," and "gratitude."
So, how does one help ensure that your own inheritors land safely on the "blessings" side? The author recommends family "open communication" and "teamwork" between and among family members, even intergenerationally.
While the article is written from the perspective of an "inheritor," there is much to glean from it when planning your own estate. One thing is certain: the failure to prepare your loved ones for their inheritance, then to protect them from it (and it from them) hazardous to your inheritors and to your wealth.
