That discussion is just an analysis of the circumstances in 2016? Trump was running for president, he was anti-globalist, MAGA and Woke were (still are) at odds and a critique of the Fed not reducing interest rates more. Those kinds of discussions happen on this forum every single day. They're openly saying "We're not getting our way on interest rates and things aren't going well in the country."
In the aftermath of that discussion Brexit went from a mere population desire to an actual executed plan. Trump has withdrawn from the WHO, he's threatened to withdraw from NATO, he's placed tariffs on China (in two separate administrations). What they're describing in analysis is the desires of the norm poster on this forum minus the negative rates.
