The EU is built on strong foundations: the four freedoms.
What are the four freedoms?
They can be divided into two categories:
1) what you put into the economy – people + capital
2) what you get out of the economy – goods + services.
The immense achievement of European integration is that these people, goods, services and capital can move freely within the EU. These four freedoms are the cornerstones of the European ideal; they affect the lives of everyone in the EU – and because they are given equal importance, they support our continent’s economic and political unity.
