The UK is rapidly collapsing and at this point is a husk of a country in which nothing works except the City banking accounts.
The UK is just developed country facing the same problems associated with an aging population as every other developed country (and also many developing countries—sucks for them...). There's absolutely nothing special about the UK and if the UK is a failed state then so too is Germany (where I live) and the rest of Europe, and the only "successful" countries on the planet are the US, Switzerland and a handful of microstates.
Well at least the trains run...
... yeah, fuck it.
