If a country hands out enormous subsidies but yet isn't leading in anything, then maybe it's time to consider what structural reasons are causing these subsidies to be squandered and whose bottom lines are being padded.
I heard that when some country wants to pay in a different currency than USD for oil, a coup suddenly happens, or a helicopter comes and the president gets kidnapped
It basically means most of the world's currency wealth is held in the USA or backed by the USA. So the answer would be the finance sector - it's subsidized by the rest of the world.
That’s a stretch for the topic at hand. You can say hey the US does this probably morally equivalent thing, but when people are talking about subsidizing domestic companies so they can outcompete foreign companies in foreign markets, this isn’t what they’re talking about.
