It's all just a simple case of UK not being able to afford itself. We're playing at being a world player when we're just a sh*tty rain-soaked little island whose only growth industries are crime, footy, pay day loans, cheap takeaway food delivery, industrial lager and cider, tattoos, online gambling and bingo. Any blue chip companies that could have sustained us with foreign earnings ( and used to quite well 60 or 70 years ago when it was "export or die") either fled or were more likely bought out by Europeans or Yanks. We have little to offer an increasingly technically advanced world in 21st century.
