That being said, I feel like we need to be more nuanced when we discuss "intelligence", because I think that it can have a multifaceted definition and people have a wide array of skillets.
So I perhaps a better question would be something along the lines of "Intelligent in what way?"
God rewards those who are good, and punishes those who are bad. Therefore, if you're rich, its God rewarding you for being good, and if you're poor, God is punishing you. Therefore, we should help the rich, because they're good, and not help the poor, because they're bad.
It's not spelled out this explicitly, but this has very much become the philosophy of the right-wing Evangelicals, and a big part of why they love Trump. He's rich, so anything he does is good, and he's really punishing those wicked poor people.
