I 'think' you make way too many assumptions about people you do know AND particularly your 'thoughts' . .. that ALL people are greedy .. .I have a feeling that you would not believe it if someone told you they were not greedy ... however, I can tell you first hand that many many people .. are full of gratitude for WHATEVER they have OR DO not have ...and Yes, It's real.
..... I realize that concept does NOT fit into your assumptions.
I am sorry about that .. as it makes for a rotten attitude, & a hard person .. maybe even a self hating person
.. . to have to believe that EVERYONE is GREEDY... hey, It's just not true..
and I am sorry that it is true in your world.. I really am. It makes for an ugly world.
