John Calvin masterfully states the problem with the love of money (i.e. selfishness) in his commentary on Exodus 1:9:
“This was common with heathen nations, to profess in their counsels, that what was right should be preferred to what was profitable; but, when it comes to the point, covetousness generally so blinds everybody, that they lose their respect for what is right, and are hurried away headlong to their own advantage.”
The Ethical dilemmas we find ourselves in are not truly a question of what is right, most often, but a question of how can we get what we want and still have the pretext of being right.
