Though migration has increased in recent decades, few politicians want to talk about the issues surrounding it.

Migration is one of the most pressing issues of our time. As a result of globalization, increased mobility and growing inequality between wealthy and poorer nations, more people migrate today than ever before. But why?

First, there is a significant disparity in income and living standards between “developing” and “developed” countries. Poorer countries often have far lower standards of living, and their social and political institutions tend to be weakened by corruption and don’t necessarily work toward the betterment of the nation.

Second, migration has become easier for those who earn good money in their country of origin. For example, it’s very expensive to migrate from Congo to Denmark; the entire process becomes a lot easier if you have some money to spare.

Finally, large, established diasporas, that is, groups of people living in a country other than their ancestral homeland, can help new migrants settle and find work in their country of arrival. The larger the diaspora, the more people it will attract.

But despite this massive increase in migration, politicians don’t seem to like talking about it. 

On the one hand, this has to do with the fact that there isn’t a lot of data about worldwide migration, as researchers dread sifting through the huge data sets needed to produce scientifically meaningful results.

On the other hand, migration is a complex issue riddled with moral and ethical problems. For example, policymakers have to raise questions like: Is it right to let some migrants into the country, but not others? Will politicians be considered racist if they don’t want poor migrants in their country? And what happens to the countries that the migrants leave behind?

These are some of the questions that will play a decisive role in determining the future of migration policies.
