Just to take the headline without the context:
being rich and being smart are not necessarily synonymous and one never required the other.
In other words, smart people often do NOT aim to be rich. They have more interesting goals and they usually either sacrifice "common wealth" for them, or are just ok with a decent amount of money. Money's nothing. Money's not a goal. Never been.
Smart evil people go after power control and knowledge. Money is a side effect. Dumb people only go after money (which comes and go, really).
Well, smart people also choose to pontificate about topics on which they consider themselves smart. If your aim isn't acquiring wealth, you may not be the best authority on the topic of acquiring wealth.
