shares, TT!
I have one voting-age grandson (still living at home with his parents, incidentally) who seems to be enthralled by Libertarian beliefs right now, although not wholeheartedly wedded to them. As I recall, my undergraduate years were when I first learned about Ayn Rand, as "Anthem" was making the rounds.
After reading more, however, I really couldn't see the point of her so-called objectivist philosophy, finding it mostly nonsense and hypocrisy.
I believe that youth and his companions are more responsible for my grandson's leaning towards Libertarianism right now than anything else and that he will, in the end, make good choices. He is basically quite sweet and empathetic and certainly has better role models in the family than most of his friends do. But it is sad that too many of his friends function along the lines you describe, without ever seeing the irony.
What is tragic is that we have too many in - or seeking - elective office who have "R" after their names and who are essentially sociopaths. Trump, e.g., seems to tick every checkbox. http://www.mcafee.cc/Bin/sb.html
