Borders protect countries from mass immigration
There is a space on earth where borders are virtually removed between a cluster of countries. It's called the European Union, a space 3,000 km wide in which 500 million people live. More than anyone would need. Within that space, a citizen of one country can leave his village, travel many kilometers, cross many borders and settle down wherever he thinks the grass is green enough. He can get a job if he feels like it, claim government support, mingle with the local society or keep to himself... his status of immigrant will barely hinder his possibilities.
This space comprises countries as disparate as Greece and Finland, Slovenia and Ireland, France and the United Kingdom, the Netherlands and Portugal. Some of those countries enjoy an excellent economic situation whereas some of them are bankrupt and suffer from two-digits unemployment rates. How come that there has not been a massive exodus of Spanish workforce to Finland? Why don't all the Greek protesters go and get a job in the Netherlands? They could, the administration is not preventing them at all.
Some do, but for the vast majority, they stay in their freaking village. Because they love that bloody piece of land they happened to be born on. People are attached to their countries and their culture. The few that do immigrate mostly miss it. Maintaining borders, visas... to curb immigration might actually be giving those on the outside the impression that it might be worth it to try to sneak in.
