Yes, we need to leave the EU.
In sum, Brexit supporters say it is necessary to leave the UK because they think the UK need to take initiatives to decide what they do and how they do without any other intervention. Though economists would worry about the outcome, there is no proof that we would fall into economic disruption. Also, the UK has spent a lot of money to be a member of the EU and it’s difficult to see what kinds of rewards has been given so far. It is better to spend that money on the UK as there are a lot of issues we have to fix. In addition, it is possible that the UK can gain much larger profit in trading with non-EU countries alone without dealing with the EU trading rules. Finally, in public opinion, there is skepticism about integration with other non-EU countries. Remaining within the EU could lead bigger influx of immigration from those countries and this could bring up some anxiety among the nation.
