No Pain, No Gain.

'A third of finance chiefs – 33 per cent – at the UK’s largest firms cited meltdown in the single currency bloc as their main concern this year, according to a survey by accountancy giant Deloitte.' (Mail.)
SO! More than two thirds didn't!

Even if the 33% are right - problems caused will have to be met at some point.  When quitting the EU eventually happens it will not be entirely pain free but it is the only way we can be optimistic about our economic future. How can losing expensive shackles, restraints, mad bureaucracy and imperialistic nations supposed to be 'friends' who stab us in the back ever be a bad thing?
