No. Lots of people from wealthy (and predominantly white) countries across the world have the same kinds of motivations.
To recognize that the existing structure of the world split between the haves and the have-nots is created only by human choices, not a natural state, is to admit to oneself: that one’s station in life is more luck than merit, that one is part of a fundamentally unfair system that one benefits from every day, and perhaps that one has a moral duty to fix it—or at least that the fix may require a dramatic change in one’s standard of living and habits and traditions.
For most people, who consider themselves inherently “good people”, that is a very tough pill to swallow. It is easier to look for other options, even to the point of some self-delusion.
