Why would a country not want to become a member of the european union?

A country may not want to join the European Union because they seek neutrality, are doing fine on their own, or are displeased with the European Union (opposed of the idea or members or just displeased with the outcome [most important example is economic meltdown of the European Union]). EU has many laws that has to be adopted by the member countries. Member countries also may have to help other member countries in financial crisis.

However, despite these reasons, almost all countries in Europe wish to join the European Union, either soon or in the near future.
