A certain group of people who practice denying greed daily would be surprised that half of their comrades might not as poor as the rest of them. Because there are different reasons for one to deny greed.
– Rationalize that you don't like something because you can't afford it, to feel better about yourself.
– Reaction formation because you are already financially exploitative to others and don't want to admit guilt.
The latter has more reasons and resources to be the head of a movement, a non-profit organization, and who executes their comrades after revolutions.
