This is happening across society, and I consider it a tragedy the people focused on race and sex have taken all the oxygen out of the room for a much needed discussion on class.
I’d even go so far as to say it’s encouraged (eg, BlockRock ESG) as part of a “divide and conquer” strategy by the capital class.
If "anti-imperialist" Westerners truly care so much about brain drain negatively affecting other countries, they should go live in those countries themselves and provide their services there for the sake of greater good. But very few actually do so, and even fewer are willing to do it on any kind of non-temporary basis.
PS. I didn't say that people calling this imperialism are from west.
