This is such an American thing that I find it hard to respond to, because these cultural things feel universal when you're swimming in them.

Wealth doesn't make it difficult to figure out what to do with your life if you never thought wealth is the goal. The problem is that the sole life goal for this person was to get rich, and now that's the endgame, and he doesn't know what to do.

If the goal, instead, was to have fun, to foster a strong social circle, good relationships, to do things for and with them, to have hobbies, to learn new things, to challenge yourself, etc, he'd just think "oh cool, now I can do more of those without having to spend X hours a day working".
