The fucking basic fact being the US /= the UK. And not everything that makes sense in the US makes sense in the UK. Look at energy. The US can support 1,298 different "energy providers" because the framework of state to federal and the spread of people and land makes it sensible.
It never made sense in the UK. A country that could fit into most US states and have another country left over.
That's before you start to look at the cultures.
If you could blend the positives of the US into the positives of the UK, then the UK could be a very different and better place. Instead we imported the very worst of the US that (re) enabled the very worst of the UK and ... well here we are. The worst of both worlds.
I say "UK", I am aware I may be more thinking of England.
