Opponents of Brexit, both within and outside of Britain, see it as doomsday for the country. They seem to think that it will cause some kind of economic collapse or regression, and whatever else they can think of.
On the contrary, Brexit will quite probably turn out to be one of the best things that have happened to Britain in a long time.
At first there might be a bit of economic instability or turmoil (or maybe even not at all!) but, I predict, quite soon Britain's economy will raise quite significantly. When Britain exits the EU, it will have complete carte blanche to make any sort of economic deals with any country it wants, without outside restrictions and control. And this is not just hypothetical. Several countries have already expressed their desire to form economic deals with Britain once it leaves the EU. If they happen, they will probably be really lucrative.
Moreover, the EU has no control or say over this. They have absolutely nothing to threaten Britain with. On the exact contrary: It's Britain who has all the power to threaten the EU, if the latter attempts some kind of pressure, sanctions or other such tactics. Britain has already expressed that if the EU doesn't play nice, Britain will become a tax paradise for European corporations. Meaning that these corporations will be free to move all their business and banking to Britain, out of the EU, for great profit. The EU would thus lose all this tax money.
And what's best (from Britain's perspective at least), this might have been the absolutely perfect time to leave the EU. The EU is collapsing. There's no way around it. It would be a surprise if the EU exists anymore, as it is now, in five years. Who knows, maybe a miracle happens and everything will turn 180 degrees and the EU will be saved and everything will become ok once again. But I don't see that happening. The EU is becoming worse and worse, and it's going to collapse. And I'm not the only one seeing this.
It would probably be wise for other member countries to just follow Britain's example and leave the sinking ship. The EU is a failed experiment. It's not worth it. The sooner that the member countries realize this, the better.
