You forget how WT like to cite Malachi 3:10, the parable of the talents and Solomon as example of how Jehovah's blessing can result in spiritual and literal riches. Also, they like to point out how it's not money that is the problem but the "love of it."
It's like a variant of prosperity theology that WT teaches. Give to Jehovah generously in all things first and he will look after you and in the case of some blessed few he will look after very well indeed.
