I would strongly advise that you complete the full Phd program if you possess the aptitude to do so... If you really want to work in industry as a physicist, a Phd will serve you very well. It's good to remember that completion of the Phd or MS shows stamina more than it shows knowledge - and employers look for the proof of stamina during resume review. So not completing the program shows lack of follow through. If you do not plan on completing the program, I would strongly advise you to get 'going' on something else that shows you have the stamina and work ethic that employers look for in new hire employees or contractors.

As a side note, I have a BSEE. Although, I did things a bit backward. I started a family first, and then discovered that a salary without a degree is much lower than with one regardless of the skills you may possess. It was a huge struggle to complete the degree later in life, even though it really wasn't much later... and completing a MS program was out of the question - even though I certainly possess the ability.
