But in the right hands a PhD is the key to the universe.

I had an marketing professor in College he demanded that he be called "Doctor".

ADVERTISING!

A person with a PhD can write his own ticket. He can take a position with gov't and leave it at that, or he can build palaces of thought and get them published. So many take a PhD and then do nothing with it. For a person with a PhD, when he speaks, he must be heard. Somebody else can say exactly the same thing and may be ignored. Probably will be ignored.
