Regarding the 'never met an altruistic person' person.
I think that speaks volumes about you, not about the society you live in.
I feel a little unconformable to go much too personal level here.
By stating that I have never met an altruistic individual I meant, I do not believe there is such a trait as altruism.
I have met a lot of different kind of people (been previously working in sales around 5-6 yrs so I have indeed met a variety of different type of people).
That being said, I do not mean there is no people participating charities, donating money to causes, helping and voluntaaring, being nice to others despite the other may not be nice to you etc.
I simply meant I do not believe there is something truly altruism. If you scratch a bit the surface you might find some selfish motives behind those seemingly altruistic actions (for instance, voluntaaring gives you a feeling of being needed by someone, donations makes you either happy or helping you to express yourself somehow - the highest level of Maslow's hierarchy of needs etc).
All I am saying is that not everything that looks good is good after all if you go deep enough.
That being said, I personally am donating in causes I want to support, and indeed the feeling after done this is heavenly and as I believe in God (however, I do not believe in doctrines but God who is simply the Almighty Creator without describing Him more) and that God will reward it at some point.
