Come to the west, get trained and return home and build something better. Doctors and engineers driving a cab in New York is so broken.
It's broken, all right, but what's broken is "home", not the west. (All right, the west is broken too, but in this situation the brokenness of the west is not the primary issue.) And they didn't that they could fix "home", so they left, and for the most part they aren't interested in going back and trying to fix it. They probably have a better perception of how hard it would be to fix than we do.
Best to ensure developing nations have their best talent to DEVELOP the nation rather to deprive them of the best people and hinder development and improvement. You take out the best people and what’s left, poverty, corruption and conflict that forces more people to leave and requires more outside aid.
For context: We occupied Japan for, what, 12 years? We technically occupied Germany longer, but practically it was about the same (I think - from memory and not researched). In that time, we transformed them from violent, racially superior, conquer-the-world militarists to more-or-less western-values democracies. But we put a lot of people in there, and we controlled every aspect of their society.
Iraq and Afghanistan, we tried to do it with half-measures rather than a complete rebuild. And it failed.
One started because we won a decisive war against the nation, in the other we invaded the country on a flimsy excuse.
We have entirely different cultures, times, mores, media landscapes, and different series of occupations, modern weaponry, 4th generation warefare (post vietnam) tactics, the list goes on.
Why would "oh we didn't waste enough money occupying a country that we gained little from" be the right choice? How do we magically know that?
If you've never lived in a poor, corrupt, dysfunctional place, you'll not understand how bad life is that'll make someone wish to be occupied.
"we could not govern ourselves" really belies how young many countries are and the unique challenges they face w.r.t. interference from developed nations. Nation building takes _time_ and I would implore you to think about the historical events that have shaped your nation.
In short term if you want to stop this particular war make UAE and Egypt hurt as they are funding the groups.
The previous colonial/imperial regime of the Mughal Empire was just as much a burden on the population.
The main reason India is able to feed its population today is the green revolution post WW2, especially the work of Dr. Swaminathan in India. Without it I think we would still see massive famines in India.
Hard to say if it would have worked, Ian Smiths comments was mostly made after Mugabe took over, so it was never tested if it would work, or if Smith was even sincere in his statements.
South Africa today is simultaneously a troubled place and yet doing well compared to many of its peers. Violent crime is very high, for example, but similar to 19th/early 20th century USA.
I think the parent comment has shared their experience which makes them think this idea might be better than status quo in their country.
