Example of Poland and guys that Sam.A. Gave shout out.

Their talents would be simply wasted in Poland. There simply is not enough capital and academic resources are not going to best people but to ones gaming the system.

I bet a lot of talented people move to US because they would have to fight uphill battles in their home countries with lack of funding, nepotism, corruption, caste systems you name it.

So I don’t think it would make much difference for the countries if they don’t have society set in ways to benefit from those talents.
