So, leaving might be good for the UK economy in the short term. Fair enough, but why should I believe that particular economic nugget when the main Leavers have spent weeks pooh-poohing absolutely every other economic prediction that's come their way?
Some remain campaign predictions will turn out to be true, such as rising prices in some imports because of a devalued pound in my opinion, but there is also a fairly sizeable chance other major currencies will be affected too, such as the Euro.
Many will be speculating Brexit could mean the end of the EU/Euro and the Euro could slump in value too.. which ironically might actually help the EU/Eurozone, since their exports will be cheaper too to the rest of the world. If the Euro stays put or even rises in value, then we can export to them more profitably even without a trade deal falling back on WTO rules/tariffs etc.
Other Remain predictions may turn out to true too, such as the movement of people/workers as well. A post-Brexit UK may have to compromise to allow a certain quota of EU citizens in or some other arrangement.
The problem with the info that emerges from the pro-EU establishment, is that it tends to be the worst case scenarios, so the voting public have kittens over them and the more probable moderate scenarios are archived for their own reference, should the UK vote for Brexit.
I don't believe any of the numbers by either side, be it the saving of the "£350 million to Brussels" from the Leave campaign or the "UK households will be £4300 richer in 2030" from the Remain campaign. They are farcical and it's deeply depressing that they get so much coverage. I'm just going with the underlying principles myself.
Brexit might be good for EU/Eurozone one way or another as it could force their hand into resolving their deeply entrenched problems. Maybe collective debt for Eurozone countries will be put in place(post-Merkel).
