Which is unlikely. If UK walks out of all this, with all the perks it asks for and even less responsibility, just for kindness, then EU will inch towards to be a bigger failure.
Of course things are going to change. As a good outcome, changes should be neutral, not punishment, but noticeable. So in other words, still hurts.
As a citizen of another EU country, it pains me to she what's happening, some people just want to blame all their problems to a common "enemy" and at that point, demagogues use that for their own gain, I've seen it and keep seeing it on my country in a grand scale.
My hope is that somehow a good deal between UK & EU comes off that which the least amount of change, but I'm probably wishfully thinking.
