I don't know... I think I can see what
@Revoltingest is trying to portray. If I can make the situation for everyone around me better, the situation would tend to become better for myself. It's almost like a selfish act that trades instant gratification for a more fruitful reward.
It seems you're talking about the societal or macro level, the ability for organizations or communities to effectively improve their own municipal. I find our humanity shines its brightest on the personal or micro level. Effect what you can, accept what you cannot.
Her argument seems to stem from the old socialist-vs- capitalist
antagonism. Socialists say that capitalism is about dog-eat-dog
competition without cooperation or concern for another. That's
the simplistic pure "selfishness" & "greed" view. They ignore
the real world of cooperation that's necessary in capitalism.
The also ignore the problems in every attempt at socialism
(ie, the people own the means of production), ie, that it has
always resulted in an authoritarian government trying to
impose control & uniformity of thought on the populace,
eg, Cuba, USSR, N Korea, Khmer Rouge, PRC.
They decry competition, individualism, greed, & wealth,
but this is just thoughtless cheerleading. They should
examine what happens when those things are suppressed
by government coercion. (Of course, the "elites" in
socialist governments lead lavish lifestyles.)
