It's hard to tell your kids, with a straight face, that education is the most important thing while you show them that it's not. He takes his responsibility as role model for his kids seriously, something sorely lacking in our time, and gets called stupid by people here.
It's not like he is going to let his kids starve because he has made this choice. They aren't going to live on the streets without the 250k.
But I bet you when his kids graduate from college they'l thank their father for being the role model they needed to help them achieve their goals. I would rather have that, than whatever fleeting thing I would have bought with the 250k.
