Brain Drain Problems The Brain drain problem refers to the situation where a country loses its best workers. For example, skilled workers in developing countries such as Iran may be attracted by better rates of pay and working conditions in developed countries. The Brain Drain means that developing countries struggle to develop because the best skilled labour leaves the economy. Thus it becomes hard to break the cycle of losing the best workers. The Developing countries lose in many ways: Less tax revenue Loses potential entrepreneurs Shortage of key workers what do you think ?
