The comment I replied to said, verbatim, in its opening line, "Children are in poverty because some people grab vastly more than their share of the world's wealth." That is literally the fixed pie fallacy. Nobody is arguing that extreme inequality is a good thing, but to say that child poverty exists due to other people literally taking their "share" of the wealth is untrue.
