Pretty sad and angry today, but you turned out indeed to be quitters.
People like you will be the ones suffering the consequences the most, so I wish you all the best!
My guess is that they are hoping that the economic loss will be short lived and people will want to continue to trade with the 5th largest economy.
My objection isn't that somehow we'll turn into a banana republic. My guess is we'll drop 3-5% GDP. It's that building growth in a slow global economy is painful. We've spent the last 8 years going through that pain and we'll just have to do it again. It's like shooting yourself in the foot but without actually being on the front line.
Where I have a feeling my view diverge from yours is that the only good reason I see to be in the EU is economic. The single market has been a success and good for the UK. The rest, not so much. I think it's a mistake to leave the EU but not an unqualified one.
It has had an immediate effect on me and my co-workers (been working since 4am). It is entirely possibel my job will move to continental Europe some time over the next few years (I may or may not go with it).
It is also entirely possible that it will cause a second Scottish referendum and possibly a Northern Irish one too. My current plan is to agitate for London to secede from the UK. Not sure that'll work though.
