In addressing the question of a man who interrupts His teaching, Jesus tells a parable of a greedy landowner.  However the parable is about more than the symptom of greed, it points to the source of this symptom.  The only thing that can cure anything for good, is a growing relationship with our Heavenly Father.  Everything else leaves us playing Whack-a-Mole.  If you want to get rid of a headache for good you have to address the cause, not just stop the symptoms.
