I'd generally agree, but my follow up question would be: which western country isn't?
Denmark?
The Swiss?
Norway?
And I was in Serbia lately, and while it was not as developed as NW-EU, nobody there described it as decaying (and many said they experiences decay when living in western nations over the past 2 decades).
Why limit yourself to western countries? In fact, why limit it to countries at all? Isn't it the most popular trope of all time to decry the state of today and romanticise yesterday? People have "not been wanting to work anymore" for at least 150 years, things were always better in the olden days, people don't make 'em like they used to, etm.
There's very little value in a statement like yours. It's a truism that has never been correct.
That it sucks elsewhere means we can't decry this instance?
Poland, but its on borrowed time due to the extreme fertility crisis.
Who said there was one?
Poland is now in the Western sphere of influence and it is not in decay. A weak case can be made for Ireland but it’s harder to extract effects of tax haven status. But Poland certainly. Going to be a higher income populace than the UK soon at this rate.
The US is unusual as a federation. Some parts decline, others rise. I think it’s resilient. And every time something goes wrong, America pulls out a magic new technology. We will see if R&D will carry the day again.
