You can argue that a true meritocracy still wouldn't be ideal (as Young did), but that argument seems irrelevant -- the problem in the real world is that we pretend that we have a meritocracy, but often the person who gets the promotion or whatever isn't actually the best at their job, but is a cousin or fraternity brother of the person in charge -- the old "it isn't what you know, but who you know".
Written in the 50s it's prescient to what has been happening since.
