Greedy for the property of others, extravagant with his own

Greed is a little bit more than enough.

The greedy man is incontent with a whole world set before him.

We're greedy and we don't like to finish second.

Greed makes one want to get something he/she has not worked for

Greedy people are never satisfied that they have enough. They’re like sharks that spend their entire life hunting and consuming. All the oceans in the world can’t satisfy these eating machines.
