I am no scholar on the issue, but a friend was telling me about the history of Sudan with the rise and fall of their socialist system through the 70's until the oil embargo. As a strong proponent of the free market and capitalism, but I think one of the ironic about human beings and what makes a free market system and capitalism is that people will work their ass off to be lazy. The thing is that once people get what they want, they stop wanting.
Leave people to their own dreams with delusions of great inventions and great societies free of responsibility. They are going to believe it in their hards and it will become a religion, and people will work till their hands bleed and keep going.
But as soon as you convince a person we already live in a perfect world, or be already got it figured out, or don't worry just HOPE because there is someone else assigned to the job; the lazy inside of us doesn't cheer (but maybe a little) but instead just says "ok, nevermind."
We don't need to encourage hardship to "watch the human spirit overcome great adversity" as I think many liberals believe what the free market is about, but leaving people alone, free to have wild delusions and make it a reality for them and anyone else that choose it for himself, or moves on to make his own dream.
I love my dreams, dreaming is one of the greatest experiences of life. There are so few things we can really have much power in this world. Why in the world would anyone want to pay (or vote) someone else to do that for me.
I can't imagine a more important purpose for our being here.
