Note that I don't say whether it is right or wrong as the idea of righteousness simply doesn't belong here (only fitness and procreation reign supreme). Further, that was not actually my point. I meant you could look at it in a more personalized sort of natural selection. If your buddies don't care about their health, look at it as your advantage if you do
Same as you, I didn't mean to bring up the moral side of the possible outcomes here. After all we are in the Economy section on bitcointalk, and not on some religious forum talking about what is right or wrong. I literally meant that, unlike in prehistoric times, there is no advantage in fails of others now. In today's world, the more people around you prosper, the more chances for you to prosper too, and vice versa
Do you really think today's world is different from prehistoric times?
I don't think that much as far as social relations and interactions are concerned. Essentially, we are still the same folks as early hunter-gatherers from the stone age, and we quickly return to that state of mind as soon as there are no more authorities and law enforcement (which technically proves my point)
But I don't necessarily disagree with your point that the more people around you prosper the better it may be for you personally (and it works in reverse as well, of course). This just shows how complicated things are in social interactions and relationships, where both competition and cooperation can very well coexist (which this forum proves)
