The main aims of the EU are:
To raise the quality of life for its citizens, through social development
To improve the economic position of its citizens, companies and countries by economic co- operation
To promote common foreign and security policies
The countries (member states) that make EU remain independent nations, but they pool theis power in order to gain a strengh and world influence none of them could have on their own. And that it's exactly the reason why I believe with all my heart that:
The majority of Spanish trade is done with other member states, so the goods we buy in our shops come from the EU. We also have freedom to travel freely and to live and work in any of the countries of the EU. many areas of our lives are covered by European laws, in particular such areas as business, agriculture, the environment, discrimination and civil liberties.
