By the time I read "Atlas Shrugged", I was already a conservative and thus, found the book to be dull and repetitive (since I already agreed with many of Rand's premises).
I disagreed with her blind assertion that taxation isn't necessary. Given the times we live in (and her too), to think that a nation's military can survive without tax dollars is foolhardy at best. I for one am glad that a large portion of my tax dollars goes toward creation and maintenance of the world's greatest military force.
Miss Rand may have implied quite strongly that taxes were somewhere near the evil category, but never implicitly said there should be NO taxes. She said taxes should not be confiscatory. She believed taxes should be voluntary and many government services should be pay as you go (the courts for example). Can you say Fair Tax?
