My proper form of government would be what works for the vast majority of people. That changes just as the world does.Rand was a nutter, who died living on Social Security and using Medicare. And the Proper role of government is whatever we damn well say it is.
Let me guess ... your proper form of government would resemble a Socialist dictatorship. And you say Rand was a "nutter?"
Study up on Rand and you'll find out that she really was a nut. It's her life, and it's documented. She never got over her self-centered childhood, her obsession with heroes from the movies, or what the Communists did to her father's businesses. Between that and her inability to make friends as a child, because she was so focused on herself, she became who she was and then tried to call her worldview the only moral one. Nutter.
There are some truths that are self-evident and that NEVER change. I believe that some government is necessary but I would be totally opposed to a top-heavy, dictatorship no matter what the century or the circumstances. I will always treasure my freedom, liberty, and ability to make decisions for myself and family without government intervention. Some law and regulation is good. Without it we would have anarchy which generally turns into a mob-ocracy. I'm not so "needy" as to need a huge government thinking for me. I also like the idea that I can keep what I work for and give to others in need as my conscience guides me. I'm not fond of giving to the charities of a government's choice.
