‘Why I do not have that thing what he has?’ This is because you think that he is superior to you because of that thing. Due to this, you wish that you should be on his place. This is jealousy – one form of lust.
What is superiority? Is it having more money when you cannot eat gold? Or is it having expensive clothes when they can crush you under mud? Is it having your order accepted when your own minister can stab you in your back? Or is it being known by everyone when they can say you bad on your back? Is it having everything that everyone have? Or is it having something that no one have? Is it superiority?
