As you so kindly called me Joe-Bob I guess I should come back ;-)
There is clearly a difference between "gene" selfishness and "personal" selfishness as expressed by wealth/material success in modern human society.
By your picture I guess you are of middle class. Your "personal" life expectancy is high because you look after yourself, but your *genetic* survival is low because your lot is not reproducing. I'm afraid that your genetic "selfishness" is positively anemic compared to more recent and comparitively poor immigrant populations whose genetic contribution to society is booming.
This is because your lot is pursuing careers, reproducing later, and having fewer kids for lifestyle reasons.
This is what I mean by selfishness. Your personal lifestyle choices- selfish choices- are causing you to fail in the genetic selfishness race. You will not catch up, indeed population statistics see your group continuing to decline while more vigorous and less selfish populations boom. Eventually they will be the majority and will assist you to be less selfish.
You say this is an imaginary distinction. No, it is a tautology, a visible trend. You will see it in your lifetime.

"... They ne'er cared for us
yet: suffer us to famish, and their store-houses
crammed with grain; make edicts for usury, to
support usurers; repeal daily any wholesome act
established against the rich, and provide more
piercing statutes daily, to chain up and restrain
the poor. If the wars eat us not up, they will; and
there's all the love they bear us."
-- Shakespeare: Coriolanus, Act 1, scene 1
