> Smaller parties look likely to gain a lot more seats in the next election.
That's true but that's more because the "two party system" became a one party system with labour doing the same as the tories. They started to become more different again under corbyn after the disaster of "tory-lite" but now they're right back to their old ways.
> I think it is not that simple. The poorly educated correlate strongly with the poor, who have done badly in recent decades.
Yes but voting right-wing is making them even more poor because the right only think of the poor as a natural resource. Yet they manage to convince them they care. Why would a billionaire care about the poor?? The only reason they became a billionaire was exploiting the poor. The only reason billionaires exist is the huge gap between rich and poor and those are always going to draw the short end of the stick.
If they voted left they would fare way better. Yet the right manages to convince them that the left only wants to take what's theirs. This image is very apt I think: https://pjhollis123.medium.com/careful-mate-that-foreigner-w...
> There are multiple European countries that have parties more extreme than the US right that are growing: AfD, PVV, Fidesz, Rassemblement national etc.
I don't think those are more extreme than the Republicans are now. They are the exact same. I'm from Holland myself and the reason the PVV (and also similar parties like FVD and BBB) is not getting anything done despite being the biggest party now, is that the coalition government waters everything down. The current government is constantly trying to grin to one another while trying to shoot each other in the back. Which is good, because it undermines their ability to do anything. I doubt they will make their full term.
