Maybe. Youngest on the list this second is 24 and, amazingly, 24 is ho hum at this point. Their career earning potential blows my mind. With 40+ years to fly, their company 401k contributions alone will be something north of $6m in today's dollars. If they max their IRAs, 401k, HSA, and maybe throw a few bucks at a 529 (not that hard to do, really), they can easily get to $12m by retirement.
