If you take the best talent from the developing world and move them all to America for education and then capture their talents through migration, you deprived the developing world of the talent they need to develop and thrive, which puts the developing world even further behind!
Seems like if we want to help the developing world we need to train and equip their talented people and ensure they have the security and infrastructure to build their homelands into developed nations with established trade routes, etc.
Or we can continue to exploit developing countries by snatching their top talent. It’s not modern day slavery, but it seems to be uncomfortably close in its exploitation.
