Peasblossom I really don't understand what people lost because of the UK being in the EU. A large proportion of our major industries have gone, but not as a result of the EU.
The closure of the mines and the steelworks had little to do with the EU, if anything. The loss of the mines had something to do with Thatcher and her battle with the unions. Steelworks closed because it was cheaper to import steel from other EU countries.
The manufacture and export of textiles was the single most important industry in the UK in the Victorian era. By the 1980s this industry had almost disappeared. Partly because other countries, such as Japan developing its own industry but also because of the demand for cheaper goods and therefore cheaper labour so a large proportion went to Asia. This had no connection with the EU.
Lastly the closure of docks.
The above are examples of major industries of one or more of these areas - the midlands, the north, Wales, Scotland and Northern Ireland. Chatham dockyard also closed in the 70s but did get funding for regeneration.
The Brits are good at inventions and ideas, the inventor of the world wide web being British for example. The best actors in the world are British and you only have to look at American programmes to see them. I don't mean stars, I mean actors who can play a wide range of roles and aren't afraid of being baddies. Just compare Alan Rickman with Kevin Costner in Robin Hood. Which one was the best actor?
In addition to actors we have some of the best orchestras, dancers and singers, artists, designers and craftspeople but the govt is cutting back evermore on funding for training, starting with schools.
The Tories have been in power for 46 of the last 70 years and must share most of the blame for not taking care of the areas most disadvantaged. Remember Norman Tebbit and his "On your bike" speech in 1973?
