How To End Greed & Jealousy

I believe one of the causes of world problems is "greed & jealousy". Let's say Isabelle is a trophy wife, and all men are trying to get her. There's a possibility that they may turn to greed to obtain more money & power to get the girl. They may lie, cheat, steal, swindle, manipulate, and murder others for money & power. Therefore, we should legalize human cloning, and clone a million Isabelles. Then every man can marry an Isabelle, putting an end to human jealousy.
