While public response as such is not a measure of quality, Rand's books have sold over 6 million copies. And a Library of Congress survey in the early 1990s found Atlas Shrugged to be the second most influential book in America after the Bible. I hope Rand's influence only grows stronger to provide the ammunition necessary to counter the statists of the left and right and return the principles and practices of freedom to this country!
The problem with Rand is that she is or was an extreme ant-statist who would not recognize any sense of the "common good". Her philosophy of objectivism is more rightly called the philosopy of selfishness. If you were starving in the gutter Rand would probably step over you and move on. Her views were not Christian IMHO.
