They take those jobs for westerners because their local companies pay them shit in comparison.

So this is going to make them poorer and cut an income source for the country as well.

But that in turn creates political and economic pressure to improve the situation.

That already existed in the first place.

Poor countries are not poor by choice. And removing avenues of financial support (and an import at that) is not a net positive.

Maybe some of them start their own companies?

"Income source for the country"? Having your brightest employed in foreign ventures is a great loss for the country.

Per the comment below some have companies formed around this work. Also, as long as they are spending that income locally they’re still bringing wealth to their country which is a good thing.

Actually it's great for the country if the income is coming back home.

I hope you say that when your job gets replaced.

Not exactly sure it's great for kenya. I made good pocket money, better than my 8 hour internship solving CS assignments. That was not a career but good pocket money.

I would just sit idle if I were not solving assignments.
