Except Elon only gets the kids for only half the time (shares custody with his ex-wife) and has a current wife and nannies taking care of the kids when he has them. He mentioned in videos that he doesn't get to spend that much time with his kids.

Just because it's possible for executives to work long hours, it doesn't mean it's healthy for their family life to.

Why does one have 5 kids if there's little intention* to spend time with them? Surely he's bright enough to grok birth control?

*I'm not a believer in "doesn't get", rather it's "doesn't want".

Maybe he was more interested in spending time with their mothers than with the kids... Very few parents prioritize their kids before themselves even if many feel that is what they one is supposed to do.

I think it very much depends on how much interaction as a father you want to have with your kids.

If you want to be cooking some nice meals for them, coaching sports, attending events, assisting with homework, tucking into bed, dealing with illness, prepping for holidays, having fun together, taking vacations, etc. then you have to devote a substantial amount of time. I suspect that most of these busy CEO dads don't spend all that much time doing these things.

You only have so much time in the day and available time that corresponds to the time the child is available and active is in very short supply.

Ah, you hit it on the head. My neighborhood is full of these types, and that's the catch - you can keep your family together, but, just like happened to me standing at the ATM yesterday, the kids ride by on their hoverboards and you hear one of them telling the other how their dad had to go in to work (again) today - just like he always has to on Christmas.
