I think it's time we changed the term "politically correct." It sounds so stuffy. How about "socially relevant"? That makes more sense. When it comes to job titles, they've been evolving for decades -- and while it is fun to watch 'Mad Men' on television and get all retro, I'm sure most women are glad they've gone from "my girl" to "secretary" to "executive assistant."
The job title tide began to turn sometime in the 1970s with the advent of the Equal Rights Amendment (ERA), but became most prevalent in the '80s and '90s when waiters and waitresses became servers; garbage truck drivers were suddenly sanitation engineers; mailmen morphed into mail carriers; secretaries became administrative or executive assistants, and so on.
