Because being frank here, most people I know who have had 30-40 years of exposure barely seem to understand the mechanics of the EU, how it worked or even how many nations it may have covered. Now of course this could be me just meeting a shed load of people seemingly all being oblivious, but I doubt it.
I guess it goes back to the initial comment you made of how if my younger generation was exposed to that many years of the EU then we would want to leave, honestly I doubt it, some would but I think firm majority would want to remain.
I think being born when we are already part of it and now knowing anything else may skew our perception and in turn is something the older generation may dislike seeing it evolve from what it initially started as, but I for one was happy with the EU as it is mostly.
Millions of Joey Essex's generation out there who haven't got the first idea about how party leaders are, so don't try and give me 'the old know nothing' argument. Come on, the young are terribly disinterested with politics, maybe not your friends but most are.
History shows that that those with most experience of the EU voted to leave, I think by the time your generation got to middle age you'd feel the same. I see no reason to over-turn the demographics.
You're a graduate, so am I. We're not really that representative, even with mass access to HE we're in a minority - there's many more young people and middle aged people who won't have any access to Erasmus, or gap years...
Your final point is an excellent one, the over 60s signed up to a common market. Regrettably, the project from the outset was always about the creation of an EU super-state. They ruined a great idea.
The EU is failing badly, it is falling apart, you can't believe at your age especially that this country's only way forward was as a part of of a failed project?
You've more confidence in your country than that right?
