Ah, aa777888 - the 'I'm alright Jack' philosophy - very enlightened.
I had to look that one up. It's not an expression we have on this side of the pond.
You've missed the mark entirely. Those with strong Libertarian leanings such as myself are among the most likely to help a neighbor or a stranger and to do folks favors. And you make a mistake by equating a desire for freedom with the selfish, perjorative form of self interest, which is 100% incorrect, and because it may be the only form of self interest you understand. There is instead something called enlightened self interest. This latter form is not incompatible with the greater good, indeed it improves on it.
At any rate I'd be happy to debate with you at length the subject of socialism vs libertarianism, but this is probably not the right venue.
