The positives? Britain managed its affairs perfectly well for many centuries without outsiders creating thousands of rules to abide by, and it can again. Immigration levels may not decline, but we can then point the finger at British politicians who can be held to account via the ballot box. The pound's currently low by design. A 0.25% base rate whilst CPI, the lowest inflation gauge, is at 2.3% equals outright manipulation. It's also called currency wars or the race to the bottom because all the major currencies are heading to their intrinsic value which is precisely nothing... the pound and US Dollar, for example, have lost 96% of their purchasing power in the past 100 years.
