Why on earth a productive company would move to Europe, where your revenues are automatically slashed by 50% in taxes, and you are constantly exposed to whimsical unfettered politicians..

They could start here. Why Facebook, Google, Amazon don't open massive headquarters in Paris, Madrid, Rome or Berlin, and they rather stick to UK and Switzerland?

Also software managers won't move to Europe for the same reasons. European politicians have the upper hand and the last word in negotiations.
