Be that as it may, this blog is about a specific paper and the strength of its claims. I don't really think puritanism has anything to do with whether this paper's model or inferences are sound.
But puritanism's remains are responsible for many of the opinions critical of the paper's conclusions. Just ask a few wealthy persons about this paper or others like it: they are usually fiercely critical and have bought completely into ideas that support their "blessed" position in society.
