European (UK) Prices

True enough, and that would explain the difference
if there was some significant barrier that prevented the supply of SM57s in the US (or wherever) from finding their way into the UK to satisfy the demand of the UK consumer. However, so far as I know, there's no such barrier. I suppose there's some duty, but nowhere near enough to explain the price difference.
And the bulk of low-cost products sold in the US (maybe not Shure mics, though, I'm not sure) aren't manufactured in the US, anyway, but in China, Taiwan, Korea or somewhere else. The UK should -- theoretically -- have a cleaner import channel from China: after all, they had a colony sitting in it for 100 years or so, and that ex-colony is still crawling with British expatriates.
I suspect the real reason for most of the difference isn't wholesale cost, but retailer markup. Retailing in the US is absurdly cut-throat. It always has been, to some extent, but the Internet has brought the retailers the great "boon" of making consumers into fluid-as-water price-chasers, and given retailers the wonderful opportunity to throw away profits in pursuit of market share more quickly than was possible with old technology.
