>citing the growth in inequality since the 1990s only makes [Krugman's (1990)] point about dollar gains/losses more stark.
Actually, nothing is different nowadays as from long ago in history: the class-warfare is still the rich (capital) waging class-warfare on the poor (labor). Krugman, whom you quote, realizes this as well and rescinded his comments from that time:
"I think our eyes have been averted from the capital/labor dimension of inequality, for several reasons. It didn’t seem crucial back in the 1990s, and not enough people (me included!) have looked up to notice that things have changed. It has echoes of old-fashioned Marxism — which shouldn’t be a reason to ignore facts, but too often is. And it has really uncomfortable implications. But I think we’d better start paying attention to those implications."[1]
"The pie isn’t growing the way it should — but capital is doing fine by grabbing an ever-larger slice, at labor’s expense."[2]
Neither of the posts you cite contradict Krugman's original argument. They merely argue that the rich have a new way of becoming richer without exploiting or the poor (namely robots).
The mood affiliation is different, certainly. But I'm citing arguments, not tone.
