Appalling nonsense.
Homosapiens* could not have survived without cooperation and action in groups, all working for the common good.
It's fundamental to human nature and how most people live most of the time.
What you describe is aberrant behaviour, which unfortunately may sometimes lead to the enrichment of the few but always at great cost to the many.
The ones who do enrich themselves at everybody elses expense tend to convince themselves that they are getting what they deserve through personal ability, but it is a delusion and they find themselves living in an unstable society and may even come to a sticky end.
It's nothing to do with altruism or elevated moral standards, it's normal intelligent animal pack behaviour; "one for all, all for one".
*spell checker doesn't allow homosapiens spelt normally with a space.
