Since the pandemic hit in 2020, incumbents have been removed from office in 40 of 54 elections in Western democracies
This is what happens. Neoliberals trap voters between two nearly identical parties. They try punching blue and life gets worse. Then they try punching red and life gets worse. Then they try punching blue...
Eventually a populist movement rises up. The more conservative party gets swept up and the neoliberal party resists. Left populists threaten power, and right populists don't, so neoliberals risk defeat by ignoring populism altogether. The populist movement therefore shifts right where it gets traction and fascism breaks out again. That's how fascism gains a foothold every single time, going all the way back to the French revolution.
The fact that Mexico was the great exception this time around with it's left wing populist government should tell you something, but apparently it's something you don't want to know.
From the Wikipedia page on Neoliberalism:
Yeah, neoliberalism isn't a "US" thing. I do have an agenda though, but it's not like I hide it.
Aside from pronouncing your own ignorance of neoliberalism as referenced above, I think it's important to note that this entire paragraph says nothing that wouldn't be just as well expressed with "you're dumb".
Empty promises were not what I would consider the exceptional or defining thing about Trump's campaign. It's also barely mentioned once in that entire article. Most of the article speaks of how unhappy people are with their current economic circumstances, not about what political challengers promised to do about it.
It's all about narratives. People are suffering economically due in no small part to economic inequality. In the US, Republicans have a story to tell about how immigrants, or trans people, or atheists are to blame. The job of Democrats is to put the blame where it belongs, with the oligarchs. Democrats won't do that, so only one narrative remains and that narrative wins by default.
