It really isn’t that hard to get a PhD…well you put in the hard work, you’ll get the degree. You don’t need to be a genius, and the training/experience you get from a PhD program is useful.

Someone using their phd to brag about their superiority is dumb, the best researcher I know only has a masters (I have a phd and I’m not as good as he is). On the other hand, I don’t think their are many PhDs out there that don’t deserve their degree, just that there are misunderstandings about what the degree means.
