I think everything you just said can be explained with reference to (and Protestant reverence for) a single verse in the Bible:
And he answered them, "To you it has been given to know the secrets of the kingdom of heaven, but to them it has not been given. For to him who has will more be given, and he will have abundance; but from him who has not, even what he has will be taken away." — Matthew 13:11–12
*I* think it is an analysis of what happens, in general, they think it is an instruction from God.
It is the basis for what is now known as The Matthew Effect.
