I sometimes go into the old heavy woollen district from time to time (I live near the edge of the area). Compared with even the 1970s, when the woollen trade was already in major decline, it is a an area of industrial decay and dereliction these days. A lot of the mills and sheds have been flattened or redeveloped for housing. At least some of this (a lot of this) is down to decades of the mill owning families sucking the businesses dry, rather than investing in new technology. Fairly typical of the moneyed classes in the UK
They attempted to make businesses profitable by recruiting cheap labour from the Indian sub-continent in the 60s and 70s instrad of investing in modern plant and machinery. They also ran twilight shifts. All this failed, as it inevitably would, staving off closures by at most a decade or two.
So to get this going again, Andy, would require massive long term investment. I can see city shysters like Jacob Rees-Mogg doing that, can't you? Nope. Thought not
