Wages are stagnant and prices are down significantly in real terms. GBP won't go very far when you leave this island, and it's not like the island produces much worth purchasing.

I'm acutely aware of this since I foolishly bought a house 6 months before the vote. I expect to emigrate within the next few months after a refinance and pay off much more easily with foreign currency.

The UK has never created barriers and does not want barriers.

Mind, of course, that so much talk of EU barriers to trade are actually required for trade: standards and international law, and further to prevent social dumping and races to the bottom in social provision. If you think the UK will do well without social provisions, you haven't seen how nasty the underclass is getting. I've had to change my commute to avoid getting attacked, I've had three scooters stolen in the past year, and almost everyone I know knows someone who's had a phone stolen.

The UK is a deeply broken country; if it was a company, only the south-east would be worth keeping. The education system isn't fit for purpose, and the mass of the workforce is not going to make it in global competition.
