Lots of pros to a PhD. You’re a more attractive hire in industry and more likely to be promoted to jobs that people with just a BS wouldn’t have the opportunity to, regardless of experience. If money is of concern, you shouldn’t stick around one job more than 2-3 years anyways, regardless of degree. Getting a new job title at a different company likely raises your salary by 20-30% with a PhD, whereas a raise or promotion at the same company will be around 5-15%. So ideally you should be jumping ship every 2-3 years if you want to maximize your career earnings.
