And do check out the whole video, it's well worth watching. England is obviously ngmi. The most far decayed country in Europe and it's not close.
That said, that particular section about Horden... you'll see Bald talk about how Thatcher sold the People out. But come on, resource economies do that. Rust belts are a thing. Towns grow and then... what, are they supposed to grow forever? A town built around a mine is supposed to disappear if the mine goes away. Now of course making the Potemkin fake door thing is incredibly fake and gay. A proper country would have demolished the town period and return it to farmland to grow crops on. Second best is just to let it die. Of all the problems Britain has, northern mine towns dying out is the least of them.
