I have no idea why would you think so, but I am pretty sure it is not a question of the belief.
Most often, the people think that helping only one person is not enough, but there they are wrong.
Because, changing a destiny of one person, may influence a plethora of the things which are only superficially not connected.
All things listed under suppression are kind of a normative, but they are only the ideological constructs, nothing of it is real.
We can't influence things out of our reach or commend. The things we can, are the one within us.
About the rest mentioned in the text ...
A person naturally born with a huge ego, will analyse from inside out, from own perspective towards other people ( you can't truly understand another, if you can't understand yourself), but one who is truly selfish, will not analyse at all.
Just my opinion.
