Completely useless, but nothing sudden about it.
Over a very long time, the nation put all its stock in services, primarily financial ones, and then decided to massively destabilise capital. So it shouldn't come as a fucking great surprise that it has a negative outcome for everyone.
Well quite. Don't do anything, it upsets the market. Such upsets concommant with the UK's EU membership. Now with out. Why bother with the whole politics thing when a junter of economists should just be left to it.
