What’s the Cause of Brain Drain?

Brain drain defined as the well educated and trained individuals leaving a poor area of the world to live and work in another more wealthy area is caused by human pride. We are told as children to work hard and we can make it out of our sad, sorry existence. No one ever talks about the need to stay in your community and and give back once you have succeded. Plus, your Benz would never survive the night on the streets in the hood.
