If you are young and inexperienced, it is also getting more difficult to get your foot in the door of a research institution without a PhD from a TOP program. Sure, there are other ways up, but getting the PhD is probably a reasonable way to approach things.

After all, how dare someone tell the grad students they can be someone without a PhD.
They are almost forgetting how's life outside the academic circles!
Now, you're late for CS 201 room 704 on that building across the campus, go and don't forget your TA notes.
In scientific articles (At least from IEEE) notice there are no titles associated with authors. It's a common misconception that you need a PhD to publish an article, there are many papers with authors in high-school.
I don't think PhDs are designed for getting a job actually. Sure, you can get some jobs easier with them, but the value of the PhD is really about the close apprenticeship you have with your advisers and other professors/grad students in your orbit.
When you actually finish your PhD, its like...what am I supposed to do next? Your circle can advise you, but you've hardly been preparing for this at all during the 4-8 years you've been inside.
You could be in middle school and publish an article. You are even allowed to make up an institution, the PC won't care at all. Heck, many conferences do double-blind reviewing now, and you know its possible to accept a paper from someone in prison (who might get disqualified b/c they can't present it, but still...).

That was a very public case. I'm sure there are other not so public.
