I think his point is that when morality gets co-opted and redefined to be a mind-control tactic of the wealthy to get the poor to do relatively meaningless things for the agenda of the wealthy, the poor stop caring about morality. That would go quite well with the point of the article about cretinism being a disregard of morality in political process; though it would also turn part of the blame from the poor to the rich. I don't necessarily agree with him, but it is a valid point connected to the article.
