It's a bit like blaming the Democrats for the political crisis in the US but I have to ask "what the hell is wrong with Labor?" The Tories have dominated politics in the UK since the later 1970s except for the Blair administration, and Blair was an honorary Tory.
There's something wild going on there, too. Leaked documents have shown how their best chance at real Labour-style governance (Corbyn) was intentionally smeared from within as an antisemite, among other things, in order to torpedo his popularity. Instead, Labour has the hugely ineffectual Tory-esque Keir Starmer now. Feels very much like a managed opposition.
The situation is not irretrievable in theory, at this point.
The problem is that in practice a solution requires the political elite to collectively admit the falsehood of the axioms they built their entire careers on.
If an individual political leader defects from the nationalist-neoliberal consensus, then they get treated exactly the way Jeremy Corbyn was. Corbyn was a soft-brexiter -- his distrust of the EU was based on it having emerged from the EEC, as a capitalist institution: what they hated him for was for being an unreconstructed hang-over from the 1970s when Labour was actually a left-wing party.
Neoliberal politicians can't admit that the crisis is rooted in neoliberal policies.
