Trump is the exception - his measure of self-worth is how much money and power he can accumulate. But for most people, money just isn't a very good motivator. Ideology, which can be almost a form of tribalism, can be an excellent motivator. For most people, "our side won" is a more effective motivator than accumulating more money that one could ever spend. But ideological tribalism can be just as deadly, as lust for money.
