To be honest, I think this running with the hare and hunting with the hounds thing I think you are doing is indictive of a lot of Leavers positions, especially when it comes to the economics. Let’s for a second (and I don’t
BTW) accept what you say that assuming benefits accrued during membership are due to membership is merely speculative. What is not speculative is that during the period of EEC/EU membership the UK did, economically, expotentially well (median income, GDP, disposal income, etc). Even if, for arguments sake, we accept that we don’t know whether EU membership was a cause of that, equally you do not know that it wasn’t the main, or even a large contributory factor to it either. The fact that someone who may have economically benefitted from that membership is still willing to support leave, despite acknowledging that it is economically at best a gamble, and despite now knowing that the generations to come who have the majority of their working life still in front of them want to remain, is
IMO the very definition of selfishness.
But equally, I understand that no amount of economic damage, companies leaving or jobs moving will make a difference to certain leave voters. They voted for leave despite all of this, not to prevent it. It was collateral damage, if you like.
