I’m not disputing most of what you said. Just saying that in each of the examples, similar events might have happened regardless, but they did things that might have contributed to the causes of the economic shock. Carter’s support for the Shah antagonized a lot of Iranians who theoretically might not have supported Khameni. The Bush admin dropped the ball on security by ignoring red flags. Trump eliminated the pandemic response team in 2018 and tried (unsuccessfully) to cut CDC funding every year including 2020. Each example is more subtle than the tariffs, and in each case things could possibly have turned out the same if they had made different decisions, but the phrasing used was “shocks that have nothing to do with a president’s domestic policy”. OK, in Carter’s case it was foreign policy.

Stupid sans serif fonts, giving me false hope.

Are those really the three examples they want to use of US presidents having no opportunity to influence events?

Sorting by new? That’s also an algorithm.

Can anyone honestly claim they expected the company would respect their privacy, when there was money to be made by compromising it?
