The Biggest Problem of our times
Selfishness and greed to some extent is good, but not to the point of self harm where your selfishness and greed hurts, alienates and inflames everyone around you, and is self-defeating.
The Biggest Problem of our times is selfishness to the point of self-harm.
We want rewards we don't deserve, and are prepared to go to great lengths to get these undeserved rewards, even when it causes long term harm. Our greed blinds us.
