If you live in Pakistan, no wonder why Pakistan has been reduced to such an economically perilous shit hole of a place. The lack of critical thinking and common sense in your assessment is astounding. There are 700K Pakistanis in US, by your numbers that would mean there are only around 550 doctors of Pakistani origin in US.Cool story but that's not entirely true. If 100,000 Pakistanis go to a country there would not be more than 50-100 people practicing as doctors. The vast majority would go on social benefits or work odd jobs as an uber or taxi driver. Those countries weigh benefits and liabilities when they decide to take immigration and sadly Pakistanis rank in the bottom as a liability. In the U.K after many many generations they are still the worst group below Africans and Bengalis in regards to employment and education
Each year around 500 doctors graduate from just the DOW medical college, majority of whom end up in US and qualify as a doctor. There are easily upwards of 10K (if not more) doctors of Pakistani origin in US. The ratio of doctors to immigrants is more like 1 doctor for 70 immigrants versus your typically idiotic lumber 1 logic of 1 doctor for every 1400 immigrant.
