Ignoring thepolitical posturing from both sides of the argument in various TV debatesand knuckling down to the core arguments that each side presents, there are some are good reasons for a British exit from the EU, known as a Brexit.
1. No single market
2. At the mercy of Germany
3. Destroying national sovereignty
4. No voice
5. Zero say over policies
While a Brexit would be unknown territory, it would not necessarily be all bad in the long run.
Britain is sitting pretty, regardless of your political lens. Unemployment is just 5.1%, which is pretty much as close to "full employment" as we can get. The EU's data agency Eurostat has this lower at 4.9%. Inflation is low, real wages are solid, and more people are able to get on the housing ladder. We are also one of the key financial centres in the world.
