hey surja,

there is nothing like that a B.A holder cannot earn more than a doctor or a engineer and there is also nothing like like that only engineers and doctors can earn more,as you know B.A is a non-professional course then and nobody as such provide good job to B.A holder to get a high paid job you must let yourself prepare for government exams as what they want is graduation and clear the exam. or you can further pursue any professional course.

good luck!
