Not true. Good salesmen love the power, convincing others to do their will. They are more like actors or politicians. You can't fake charisma just because you might get paid more.
They like to get paid for it, they can even be greedy. They like to get recognition for it, that can go to far too.
But they also enjoy making the sale.
to me, hacking > sales (no, charity/non-profit/giving away money doesn't count -> there's moral incentive there)
