In term of money, definately it is better to go for job rather than doing Ph.D. If you are looking for the R/D (Research and development) , policy making, type of job it is better to do Ph.D.

  But it is true Ph.D. is not a job oriented degree but you can attract the people by doing high level research. They will hire you if you have a good research.

If you want to do Ph.D. in high profile university like, MIT, Caltech, Burkely, Standford, Harvard, the story is different. You can't compare their Ph.D. degree with Masters.
