I think the free market is the best way of allowing people to voluntarily serve the needs and wants of others. But freedom is meaningless without justice, a concept that seems to elude most so-called "conservatives" who endorse the status-quo, and the system we have is most certainly unjust.
Governments operate using coercion, because everything they do first requires the involuntary separation of wealth from the general population. It is my opinion that given human nature, the tendency is for government power and influence to grow perpetually, and eventually become tyrannical. Even if we are to presume, contrary to human nature, that politicians could operate a large collectivist government for the public's benefit, they have absolutely no way of knowing what I need or want, or what anyone else does, and thus central planning fails even when it is benevolent.
Even though I may disagree with some of your politics, I respect the fact that you're honest.
