Just a little indicator of the damage Brexit is already doing.... A company local to me, Surrey Satellite Technologies, who have built the payloads for all of the European Space Agency's satellites, are now locked out of any such projects because all participants need to be in EU member states. They're looking to move parts of their operation to Europe so they don't lose this part of their business but there's no chance of them being involved in anything in the near future because of the uncertainty around our status.
So for anyone saying "let's wait and see" or "it all be fine in ten years time when we've got trade deals with Costa Rica and Nepal", consider what damage will have been done well before then.
Oh, and while I'm here, T-Bag's implication that EU nationals had "jumped the queue" in finding work in the UK is an appalling slur on people who have contributed immensely to this country.
