It's not that white privilege is real or not, but that there is no reason for constant articles about it on hn. In this case there was a "life hacking" angle, but as far as I can tell the author is applying this label to someone who isn't really related to the life hacking movement. So while not intentionally click baity, the title makes the article seen more relevant than it is.

This post is really weird. He keeps emphasizing the fact that when he was younger he had no such power, now that he's old he can boss people around, but somehow he puts that under "white privilege". He was white when he was younger.

I would say this is age privilege. No one wants to fuck with old people regardless of race I think.
