That's very interesting. I feel like being handed FI at a very young age could go either way. Either he realizes what a gift he's been given, or he squanders it because he doesn't. I don't think that I would have appreciated it at that age myself.

Of course, it's your choice to make (and I definitely don't know your situation or your son's situation), but it seems to me that a big part of FI is the mindset, not the money, and I'm not sure you can acquire the mindset without going through the frugal living.
