The individualism in Libertarianism is dangerous and does not take into account how interconnected we are. Your neighbor's welfare should be in your interest because if he fails, so do you eventually. The domino effect is happening right now, and even on an international scale due to globalism. Consider social programs an investment. Even though YOUR tax dollars are funding local public schools (and you the libertarian is pissed because you have no children), an educated population does affect you. Look right now! We can't compete in the international market because education is so poor.
Besides, do you know what socialism is? Did you know that there is no such thing a pure socialism or pure capitalism today, but we employ both kinds of economic measures depending on the state of the economy? Did you know that the largely Socialist New Deal program under FDR was what got us out of the depression? And did you know that all socialism means is nationalizing some aspects of the economy to ensure just distribution? It's not the end of private ownership. Socialism is not a form of government, but an economic system. You can be a socialist democracy like much of europe and Canada.
And punishing success? Nobody wants to reward the lazy! Let me give you a few statstics. The ratio of executive to pay to worker pay was 40:1 in 1980 and now it's 500:1. Keep in mind that real worker salary hasn't increased. Is asking legitimate questions as to why WORKERS salaries haven't increased and why that disparity so huge radicalism? If so, you are the perfect candidate for feudalism (and you wouldn't be the ruling class).
