Is it a bad idea to get a PhD? Hope this doesn't fall into the category of personal advice, but I just have  a general question about academia today (particularly in Philosophy). 
I have read many articles on the internet indicating that it's extremely difficult, if not impossible, to find a tenure track position in a relatively highly ranked university (top 100 nationally, say) after completing a PhD in today's job market, even from a very highly ranked program. Is this true, and is it a bad idea to get a PhD if the only thing I'd be able to do with it is teach? Does the internet exaggerate how difficult the market is? Would I have to move across the country, potentially, to find a T.T. position somewhere? Thanks.
A PhD is a research degree; it’s a piece of paper that says “this person is a competent researcher”. If you want to go into a field where being a researcher is important (e.g. corporate R&amp;D), then it’s worth your time to get one. If you’re not, it probably isn’t.
