I know from the outside this seems very simple, but it's more complicated than that. Certainly, if the objective is (merely) security for one's children, that can be secured with much (much) less money (and likely was secured in the secondary that the author makes reference to); having nine figures of wealth is not an unvarnished good, and in particular makes raising grounded, self-reliant kids pretty complicated. To appreciate this dynamic, read Graeme Wood's outstanding 2011 piece in The Atlantic, "The Secret Fears of the Super-Rich"[0].
