Along those lines, Money, in a man, leads to general wimpyness and inability to keep a woman happy or satisfied. All heroes are poor because thats how you satisfy a woman.2 big exceptions:
a) The last verse of a song, where money, wealth, power etc are good because the characters are generally sick of being in a folk song anyway.
b) If you are a woman, money is almost always good because it helps you afford those poor, heroic, satisfying types with a heart of gold.
Women with money are especially good if the song is about drinking as they represent the tipplers retirement plan.
