Every liberal does it too, from center right radlibs to far-right “conservatives”: the most extreme right fringe liberals hate the mainstream liberals for not being bigoted enough, the mainstream libs hate the radlibs for not being cruel enough, and the radlibs hate the left for not being chauvinist enough.
Denouncing chauvinism in particular is like a liberal moral event horizon, a cardinal sin against their self-interested belief in the righteousness of the imperial hegemon that keeps the treats flowing at gunpoint.
The “first world”. Countries which historically industrialized first, were able to colonize less “developed” countries, and thus have a more or less stable economic advantage in terms of dictating an unequal trade regime. This is the true reason wages and cost of living are lower in the “developing” world. These countries were basically opened up to international trade at gunpoint, forced to rapidly industrialize, and forced into being a source of cheap labor and resources for the imperial core.
