"more motivated" you mean richer. Moving to the other side of the world, when there are other closer options of "wealthy western country" to choose from, requires a certain amount of capital. I don't know if you've ever talked to poor people, but they don't tend to have the money lying around to go wherever.

Richer yes, not necessarily anywhere close to rich by Western standards. I don't know if you've ever talked to migrants - it's often a matter of lifetime savings and plenty of borrowing to get that plane ticket 

The idea that it's necessarily cheaper to move to a western country that's marginally closer doesn't make any sense
