Per my recent post on the bragging thread, our son will far outearn us in his AI career. Perhaps we should consider him part of our retirement plan. 
It’s clear on the retirement threads that we all have different views on our financial legacies. We always told our son that we didn’t work hard all our lives to make him rich. Instead, we provided him with the best education he could consume and taught him early how to build his own wealth. He’s doing quite well with that on his own. He’s an only child so, of course, he inherits everything when we pass, but we plan to die with just that dollar I posted above.
