Though I currently reside in USA, I have lived for a number of years in the UK (dual citizen)
Though the plumbing maybe antiquated (among other slight annoying inconveniences) it is
certainly not a shithole ...quite the contrary imo.
If you turn off the news and ignore most internet content the UK, along with many, many other places, suddenly becomes fucking marvellous.
Clean water, sensible weather, tectonic stability, a vaguely dependable legal system, no one starves to death. What more could anyone want?
If you let some Twitter and Daily Mail whining colour your opinion then that's a pisspoor show. What the internet and media is trying to force you to perceive is totally different from what almost everyone actually experiences.
