Moral Money Management?

I’ve been contemplating the republican “trickle down theory” trying to make some sense of it in spite of the lack of evidence that supports the concept.

I’ve come to the conclusion that a fundamental basis for this theory is that those with money, spend their money more wisely, and in their wisdom, their spending is better for society. This would imply, then, that those without money spend what they have unwisely and that their spending is purely for self interest.

Any thoughts
