Migration has become ubiquitous nowadays where every day thousands of people move from one country to another in search of a better quality of life. In this case, the developed nations may source all their manpower from the poorer ones which in turn, can result in a scarcity of skilled workers.
Brain drain is a much-debated issue and many people believe that developed countries should not provide work for skilled professionals from developing or poor nations since they are better utilised in the homeland. I personally believe that this system should be stopped as it would make poor countries poorer while rich countries would be richer in long run.
