Wisdom and making money are often somewhat at odds to each other. I am reminded of a TV show with two guests, one selling gadgets and the other a famous author. It was a disaster. The famous author kept saying "Why would anyone do that? You can just do blah instead and it's better for thus and such reasons." But you can't readily make money off of blurting "This is a better method for X that takes less time and hassle and doesn't involve selling a gadget."
