This boogie-man makes perfect sense when viewed through the lens of zero-sum thinking. They literally view helping other people as being detrimental to their own position because it means that the people "beneath" them are now less far beneath. This makes their position feel less lofty because we've raised the floor of human suffering, thereby making them feel less advantaged and less high above that floor of human suffering by comparison.

It's not even a meme to characterize them as saying, "the suffering is the point" when they support certain inherently evil consumerist practices. They literally think that way.
