Privileged Liberty

According to Charles Fried, the author of The Nature and Importance of Liberty, "liberty is an expression of what is valuable about us as human beings. It is a natural law idea; that is to say, it is a moral imperative based on what is fundamental (another moral idea) about our human nature." and this past week in World Studies and World Literature we've heard a lot about "liberty" and what it was coming from these privileged congressmen. In World Studies we also discussed the matters of the liberties of the women. We discussed this through a reading of a letter written by Abigail Adams to her husband John Adams. In the letter it stated that her husband not forget about the ladies, and remember all men would be oppressors if given the opportunity. Through her readings you were able to conclude that the women, well the white privileged women (as the non-white nor privileged women were probably treated ten degrees worse), were not being treated as equals to the men, thus they were not given the equal liberties. So I raise the question of whether or not liberty is really a natural thing that is fundamental for everyone, or if it's to those who are privileged?
