To be fair people are blowing this thing up way to much.
Yes Ireland exports to the UK and quite a bit but its only 14% of their total exports: http://atlas.media.mit.edu/en/profile/country/irl/
The total exports are $19.2B but seeing as of 2014 Ireland had a positive trade balance (and we went up in gbp with 6.3% and 4.5% in the last 2 years) of $69.7B in net exports we can take that hit (I am sure we can start exporting to other countries like we do with the other 76%).
That being said .. our nr 1 import destination is .. the UK with $24.3B which we could start importing from other places that are actually in the EU.
Yes it will cost money and yes we will need to adjust our importing/exporting but we still have 2 years (at least) to do so.
If the EU economy tanks, they end up like Cameron. The alternative is to come to a deal that both sides are okay with and then fudge it by bringing the public conversation around to the benefits of membership over a partnership to other EU states.
So the EU are going to risk further economic issues in the EU with euroscepticism on the rise? Do you see that the bargaining power is not as one sided as people think?
They built the world that the young and dumb are frittering away, and are spending their golden years still trying to move the sharp objects out of their children's oblivious paths.
There's really no way to spin this around by which the 18-24 year old vote is actually more competent in their decision than the 58+. Your only real case is "you have to let us fuck up our lives so we can learn". A chronological-but-in-no-other-ways adult voting on the referendum who doesn't even remember a time before the EU knows more about what's right for the UK than people who lived through thick and thin and maybe even remember hiding from the Blitz? Really, that's what you're going with?
