The desires that arise from envy are the need to control. Material goods, influence and power are all tools to control others. When an individual does not have control over another, then he or she becomes envious. Envy leads to anger and hatred. It leads to greed and selfishness.
Covetousness creates needs and wants that seek to fill the vacuum within the soul.
This vacuum, the love of God and neighbor can fill. Many consider that a sense of wellbeing depends on what one has and what one doesn't have. Peace and joy are relegated to passing emotions. All that covetousness does is to leave the soul with sadness, confusion and a sense of hopelessness. The soul comes to this deep realization that God is the only Shepherd it needs to follow.
