The catastrophe that people are mostly worried about is the impact of Britain leaving on the EU, not just to Britain. It is a key member of the EU and it's exit could be very destabilising for trade and investment throughout the region. On the global scale, not too many people will benefit in the next 5-10 years, maybe Britain will though (who knows for sure).
