You know, you might be right, but "hold out and this'll reverse itself, don't worry" never feels like a reasonable course of thought in such times, does it?
Well there is plenty of reason to worry. The brexit vote set in motion a chain of events that nobody can really guess the consequences of. That's a pretty reasonable reason to worry. When looking at the event itself its easy to get tunnel vision and see this as a final event instead of beginning in a chain of events that can be reversed or end up an completely different outcome. I think just as interesting will be to see what happens to some of the other less happy countries in the EU and see if they follow suit. As it stands the EU is unstable and will either fall apart or have to be bound toughener in a stronger union. IMO both outcomes are equally as likely so its hard to guess where things will go.
