actually most people are average in these aspects, according to the bell curve. Thinking everyone is dumb is an easy was to become arrogant yourself.

It's just a saying I thought up.
For me personally, I think the general populace is generally deemed by society as undesirable, that's why most people are low income.
Even intelligent people I know generally have a hard time.
However, it seems attractive people have easier lives generally speaking.
And in such people who are attractive tend to not be intelligent since they've never needed to be but there are a rare few who despite everything are both intelligent, abd would be considered generally attractive.
