The basic "live and let live" attitude is what really defines a libertarian, the idea that I won't tell my neighbour what to do with his life as long as he doesn't try to tell me what to do with mine.
That makes sense in a world where the individual and their neighbour are blessed with the same or similar [modern] tools in which to succeed.
But [hypothetical] smart old me can look over the fence and see that my neighbour isnt blessed with the same tools I have.
Is it not my responsability as the genetically/socially/nepotistically/whateverally elected leader in this relationship to share the spoils of my enhanced tools?
Dont get me wrong, im not asking for traditional methods of wealth redistribution (the long list of failures BBS has at the ready for just this thread); but more holistically in a modern society (looking mostly at the west/developed nations here) is it not the duty of those with advantages to help those without? Are we not smart enough now that we cannot come up with viable social structure that is just as growth orientated yet accounts for social issues as well? I guess breaking it down even further Im asking is "We are technically powerful enough, can we not just ditch the whole survival of the fittest [see: smartest] thing now?"
