I'm sorry that you did not perceive that I was being a little facetious. You must have lived in very sheltered circumstances if you have never heard someone say something like "we don't make anything any more".
I hear it all the bloody time. That's why it winds me up so much.
I am not a Brexiteer and have no sympathy with the Brexit philosophy. It is characteristic of English (not the language)
The thing is I hear "we don't make things anymore" from all sorts of people, not just Brexiteers. It's a such common trope, so much part of received wisdom that one somebody says it, I assume they believe it to be true. In reality, British manufacturing has grown in real terms almost continuously since the war with a blip at the beginning of the Thatcher era and another one after the financial crash of 2008.
I'm sorry, but it is one of my buttons and you pushed it.
