Doctor versus a simple business degree. Humm, where to start. I did my BBA from an American University, Eastern Michigan University (Better than IBA or LUMS) as I am based in US, (Pakistani Origin). Been in US for the past 27 years. I know you live in Pakistan, but there is still some relevance. So, dear friend, and Muslim Brother, there is no comparison between the two fields. I did my BBA, and did not find any job in USA, and some of my friends even did MBA in USA, and ended up working at Ice Cream Shops, Baskin Robins.
So, I decided to forget about finding any jobs in US with my worthless BBA degree, which was incredible waste of my time. It was getting too late to go in medical Doctor field - as I was in my mid-thirties and medical doctor takes 11 years to be completed in USA, fully certified and post residency, so I chose Nursing, in US, I am Male Registered Nurse Now (By the way, Nursing is highly respected field in USA), and Alhumdulilah I make very good money, but I also wish I had become a doctor in US, if somebody had guided me when I graduate from High School in US. Doctors in US make 3 times more money than Nurses. Newly graduated Nurses make on average $67,000 in US which is not bad (67 Lakh Pak Rupees per year), but Newly graduated post residency Doctors make over $200,000 (2 Crore Pak Rupees per year) in USA. But I hope you get my point.
BBA, if they find any job in US, they make minimum wage, barely surviving salary. So choice is yours. Listen to your parents. It will take a while, if you are smart enough to even consider being a Medical Doctor, and see how many people in Pakistan become doctors (Not a whole lot), versus how many become jobless BBA or even MBA degree holders (A whole bunch of them), then you will be able to decide better, Insha-Allah. May Allah (SWT) make it easy for you to decide. Remember Jaaldi kaa Kaam shaitaan kaa. I wanted to graduate quickly too, but I learned my lesson the hard way.
