I mentioned Canada and France. Could also list other countries like Austria and Netherlands that had similar issues. Hell, even Brazil, who had been improving economically and especially for its poorest people consistently since the 90s, and was taken over by a far right government that rose through social media, exactly the way Haidt describes.

My point is that what we are witnessing here is better explained by the sudden access to social media rather than socioeconomic deterioration. By the way, we agree that the working class in the US (and UK) have also experienced a relative decline in the past decades.

The right wing billionaire media blitz really took off with Rupert Murdoch and Fox News. That's the engine that has been driving a lot of it, and it is obviously transnational and doesn't know any boundaries (Murdoch is Australian). And it got started in the 90s before most people had discovered the Internet and before social media existed. The shift to neoliberalism also started with Blair and Clinton, but affected most of Europe and the Americas through all of the neoliberal institutions, including the EU, the G7/G8/G20, the WTO, agreements like NAFTA, etc. Social media didn't change the trajectory of any of that, it only accelerated it.

No, the left-most party in systems that were right – center or right – center-left getting fully on-board with neoliberalism happened with Blair and Clinton, but neoliberalism dominated the same states from at least Thatcher and Reagan, respectively.
