I don't know why we even should think about this guy? it's his choice, we can neither judge him nor change him.

Why should we think about?

and by the way, sometimes I have the same bigger concern or browse "cool cars" in internet. I cannot be a smart 100% of my time. I'm human and I allow myself to be smart, stupid, fool, evil, angry, happy.

We're all just human and we all have our natural properties like I mentioned above. Rich, poor, educated are an additional(additional to natural) social scale for measuring something.
