Do you realize that at the time of admission into medical colleges people are just 18 years old! At that age they arent sure of what they are getting into. So many guys get into med colleges and drop out or start working for pharmaceuticals after graduation. Most smart guys actually go for USMLEs or australian boards and get out of the country. So for you to blame rishta seeking mbbs girls for not serving the contry is totally unjust. So many girls go into engineering, law, other majors where they DON’T actually end up working at all. Do you know many women are enrolled at karachi university? Thousands and thousands. Aren’t they wasting the tax payers money?
And if the majority of women doctors weren’t practicing, they would have been a severe shortage of women doctors in the hospital but thats not the case. There are tons of ob/gyn in pakistan, I have never had a hard time getting an appointment with any. If majority if girls were in it just for rishta, there would have been a severe shortage in gyn/obs department because pakistani male doctors almost never go into that field of medicine.
So your theory of women wasting seats is totally flawed.
