I urge people to check out Sweden once in their lives, it's such an open and fair place in comparison to most countries in the world. Even though I'm reading a lot of anarcho-capitalist theory recently (yes, because I like Bitcoin) I still believe all of the liberals miss (or subconsciously omit?) some fundamental social truths which the Swedes seem to recognize pretty consciously.
Could you give some examples of the social truths? I'm not saying you're wrong, but I'm finding myself becoming less and less liberal and want to know what exactly you're talking about.
To me it ultimately boils down to fairness and having a sense of "being in this together". A very good example to me is the firefighter mentioned in the article, he probably does a much more productive job (saving lives) than someone like myself who might get lucky in playing the entrepreneurial / technologist bootstrapping game by striking it rich with some cost-reducing / profit-boosting tool-building. Alas, it's problematic to make these kind of comparisons though (you could argue some tool saves even more lifes, etc).
The "smells" of extreme ideology..
In any case I still believe it's fair to try to spread the wealth more evenly as you and I couldn't even build stuff without the solid framework of society.
I answered your question somewhat in another comment in this article's thread:
