Hellllllloooo ok so abt brain drain this is what i know
Brain drain causes countries, industries, and organizations to lose a core portion of valuable individuals. The term often describes the departure of groups of doctors, healthcare professionals, scientists, engineers, or financial professionals. When these people leave, their places of origin are harmed in two main ways. First, expertise is lost with each emigrant, diminishing the supply of that profession. Secondly, the country's economy is harmed because each professional represents surplus spending units. Professionals often earn large salaries, so their departure reduces consumer spending in that region or the country overall.
