“Has he been net positive for humanity overall” would be be clearer that it’s looking at everything he’s done so far
But I actually think it’s more interesting if it’s an ambiguous question. The stuff he’s done so far is significant but not necessarily aligned with what he’s doing now and what he might do or intend to do in future. The trajectory he is on now is… not upward. The influence that he has now isn’t necessarily more than when few people knew who he was, and he sounded more strategic as well as more amicable then. And the stuff he may or may not do in future is speculation.
Think the main reason it doesn’t get talked about much is that impoverishing other countries was baked into the whole “America First” idea in the first place, including the [obviously incorrect] beliefs that trade is essentially zero sum so making these countries poorer is necessary to make Americans richer. But Trump also got votes from a lot of Americans whose main concern was rising prices, so it’s particularly salient that the first major effect of blanket tariff increase on consumer goods will be their cost of living going up...
(I think also the effects of US tariff levels on the typical <$2 a day person are relatively indirect: most of them aren’t involved in direct exports to the US from countries likely to be major tariff losers, especially if he turns out to be far more interested in restricting imports of Chinese manufactured alternatives to US luxury goods than cheap foodstuffs. Lower global economic output will slow their local economies down too, but that impact feels less tangible, and to an extent is balanced out by other factors like China’s increased interest in trading with the global South and whatever happens to energy prices.)
