I think some of them honestly think that the price of modern technology and other perks of post-industrialism like fancy smart phones or new vaccines should be paid for by the global poor through labor. It's not just the "the west worked its way up from the bottom/" chauvinism entirely on its own. It's also the benevolent capitalist boss-worker narrative but viewed through the lens of nations and peoples. "We gave them a factory and taught them how to work it, why shouldn't they be grateful?"
