Depends on what you mean. If "the poor" live better, thanks to more rapidly advancing technology, in a libertarian society than in a "caring" one, have you helped anyone?
Remember that the degradations of slower technology development per capita in more socialist countries are partly ameliorated by technology sharing. They get a "free ride", so to speak, getting the drugs, the iPods, the whatever, even though their economies, per person, are less capable of generating these advancements.
Hence they don't look as bad as they actually are.
Like religion, it's 99% hot air. Just as people can go along for their entire lifetimes believing God exists, laboring to donate money to help this infinite creature, limiting their own lives in what they do in their private lives, etc., can people live an entire life convinced of some political concept, even, as per religion, it harms and hampers them as a parasite would.
"Civilized" society has learned to let people be free in choice of religions, or none. It's time we did the same for politics.
(some long stream of words), and therefore you must believe in my god and give money to me, his representative, or be placed in jail, is now rejected.
We should similarly reject (some long stream of words) and therefore you should be forced to join my health care system or be placed in jail.
Nobody sits around arguing about which god everybody should be forced to worship. Humanity won't fully progress until it learns the same about politics.
