ag,you missed your calling. You really should have been a comedian. Yes, there will be economic pain in the UK, but the idea that they'll be desperate to join the EE (European Empire) as a result is ludicrous. If nothing else, it'll be easier for any excess labor to come to the US than the EE and I doubt we'll be any tougher on illegal English immigrants than we have been on illegal Irish immigrants in the past.
The notion that the UK is without options at this juncture ignores the "new" reality. The UK has far more cards to play than the the EU and all of the EU's expose it to engaging in the very behavior that nationalists accuse them of.
