When you're rich, you're effectively smart. Money purchases brilliant financial advisors, attorneys, accountants, engineers and sales people; it buys you enough investments that at least one is going to make you look like a genius when it pays off big-time. Actually being charming or smart is a bonus; just being NOT dumb and NOT jerky ensures you'll be rolling in it.
I mention this because the world's second richest man is basically a stereotypical right-wing teenaged Redditor.
