your assuming that these 'brains' will find a use in their home country, and that's where your wrong. 1) no one is forcing people to move out of their country.

your assuming that these 'brains' will find a use in their home country, and that's where your wrong. 1) no one is forcing people to move out of their country. it's a personal choice of each of these individuals. 2) as a real life example, in my home country I know of plenty smart people with or without diplomas that ended up in jobs that have nowhere near close of a place to use their 'brains' even if they really want to and not from a lack of trying just a lack of opportunities. what good is having having a sharp brain and a PhD if the only local job opportunities are: door to door salesman, fruits and vegetables vendor, cashier, farmer, goat herder, working in a call center.
