That's nonsense, because the Muslim and Asian world send their best and brightest to United States colleges to be educated after which they stay here because they are offered shitloads of money in the tech and financial industries. It's delusional to think the way you do because it's not at all based on reality. Have you ever visited the Yale or Harvard campuses and looked at the student body walking around? And BTW many big U.S. companies in tech, pharmaceutical, and financial industries offer jobs to college valedictorians in these parts of the world and U.S. green card legal expenses and moving expenses prepaid plus starting salary of well into 6 figures and housing. I know because I have deposed these people. You horde the smart young people and what you say will happen will NEVER happen.
