It's also a wasted opportunity just from a competitive standpoint. Brain draining the shit out of Russia is a totally valid strategy that boosts the host nation while hindering Russia.
Some of these Russians would go on to make millions, and then the foreign governments would threaten them with sanctions and seizures just the same? Such a ridiculous double standard.
Expatriate Russians all over the Western world are being cancelled by Xenophobes with Ukrainian invasion as a convenient excuse.
It isn't also far fetched that the millions one might make may also get called into question just because of their nationality. The West's politics is further fueling this hate-filled divide; ceding air-time, socio-economic pedastal, and political will to the intolerant amongst us.
