Focus on current employment numbers is very short sighted, the EU needs to capitalise from Brexit. Employment is where the business is, and that business needs to be in Europe. The financial centre of Europe needs to be in Europe, the biggest airports of Eirope need to be in Europe. Heathrow is now outside of Europe, a competitor like Dubai or Istanbul. The UK airlines are competition just the same, and need to be treated that way in the future. You wait, populist will gain power in Europe as well, just like Boris and Donald, European countries will now get more inward-looking as well, the gloves are off and it is 27:1. Just wait a few more elections, most importantly the French one. Make EU great again. What goes around comes around.Nationalism is contagious, that is what Brexit fans not yet understand.
But of course you might have a personal interest in keeping the status quo, fair enough.
