it's offshore. While what and how certainly have an impact, the real problem is why. For almost all, the reason they did it was to cut costs. They didn't employ furriners because of their skills, knowledge, integrity, work ethic, blonde hair, high cheek bones, dusky skin, or epicanthic fold.

They did it because they were cheap.

While foreign resources are harmful is an accurate statement in this situation, it misses the point. The only people who get any real use out of it are nationalists and isolationists.

The real problem is the UK industry found another supplier, better still they appeared to be cheaper, so they switched.
Now they are looking for an alternative, or even just a bit of competition, they just noiticed their orignal one went bust.

Don't panic mate, if they start addressing it tomorrow (if you believe that I have this bridge), you've easy another ten years, and all you are going to do is get more valuable.
