On this point, I wouldn't say that CS PhDs are necessarily having a hard time finding jobs but rather CS PhDs aren't by themselves particular valued in industry so you generally aren't going to get your time and money's worth immediately after graduating (i.e. you'll get paid somewhat less than someone who spent the same amount of time in industry that you spend getting the PhD).

What it can get you is opportunities that people without the PhD don't have available (like corporate research teams that only hire people with PhDs or put them into a separate class called "researchers" vs. other people who are hired strictly to write code).

Whether it helps you longer term in the positions that are available to non-PhD holders entirely depends on you. I've seen plenty of people with PhDs struggle to advance and plenty without PhDs excel while working in the same environment.
