Weirdest political take I've ever had, but European far right leaders aren't "dollar store Trumps". Unfortunately, they're often fairly smart individuals, with great academic records and very well regarded in their areas of expertise. Very unlike Trump. Which makes them all the more dangerous, because they don't make the same mistakes that Trump somehow gets away with on the regular: no real life actions that go against their purported ideals (cheating or banging pornstars, for example), no blatant involvement in corruption or financial crimes either. Even in the way they speak, they're often vague enough in their (authoritarian) statements that they can still claim to hold democratic ideals and get away with it.
I don't think the UK is a great example of European politics, simply because UK politics is more akin to US politics than to any other European country's politics. Despite the UK technically being a multi party system, in practice it often acts like a two party system.
Outside of the UK, there's many European countries - let's say, as an example, Portugal, Spain and France - which have historically been governed by moderate parties, either on the center right or the center left (left and far left respectively on the American political compass), which have fundamentally failed to solve the respective country's problems.
Portugal, for example, has been ruled by its Socialist Party for most of its democratic existence. Despite that, it's currently dealing with chaos in its healthcare system. There's a general lack of doctors, hours long emergency wait times, years long surgery waiting lines, all because of a fundamental failure in creating a good way of financing the healthcare system. Governments in Portugal, both socialist and center right ones, have until recently mostly agreed on the idea that healthcare should be free. But Portugal has never been very successful economically - which means supporting a free healthcare service has always been way more expensive than the country could financially handle. For a long time the problem of financing the healthcare system was simply postponed. But now it's reached a point where many of its hospitals are in debt, it's been unable to give any raises to any of its staff for years, these staff have been leaving in droves for the private sector, it's been incapable of financing many medical acts, in many hospitals even basic maintenance has been indefinitely postponed, etc.
While I still fundamentally agree with you that people are fools to trust the far right, I do understand why there's such a big distrust in traditional moderate parties, given how much they've recently fucked up in dealing with many of the core issues in our countries - regardless of whether they're on the left or on the moderate right.
