Not sure if it’s evident in broader statistics yet, but I think that because Tesla got the early adopter market (tech savvy people), they are now losing that same market first.
I had a party at my house a couple months ago, mostly SF tech people. I found the Tesla owners chatting together, and the topic was how much FSD sucks and they don’t trust it.
I asked and no-one said they would buy a Tesla again. Distrust because they felt suckered by FSD was a reason, but several also just said Elon’s behavior was a big negative.
If you were to take exports as a good proxy for “global business interests”, then the USTR would show you that Chicago exports 57.9B in goods, making Chicago’s exports almost 1/3 of Rome’s entire GDP.
