PhD is only a recognition of a persons total knowledge,dedication and devotion to the subject. it takes anything between 4 to 8 yrs to get one after a masters degeree.most indians get it only towards their mid 40s, that too after a great struggle.there is hardly any incentive to get one.it is true that non PhDs do better in corporate life at times.after getting a doctrate, people teach,work,write papers,conduct seminars,assist as guide, do research,and write books.it is not that they sit at home and while away their time.all these activities add value to a person.we need to encourage students to get a doctrate, and get involved in teaching and research.keeping a time frame maynot be a good idea for PhDs
