Yes, I have observed greedy behavior. I do all the time, my dad is very greedy.  He makes a lot of money but never wants to spend it.  He is getting ready to move to the mountains when I graduate and is trying to save all the money he can.  He makes as many budget cuts in the house as he can.  Like during the winter he doesn't turn the heater on much to save on the electricity bill.  He has a lot of money it's just every dollar he can save he saves them.
