In Europe, around 13 billon euros have been invested in the last 15 years to reinforce the borders to prevent migrants crossing. As such it has been highlighted by a journalist team that has released the investigation project The Migrants Files, published in the Spanish newspaper El Confidencial.
The gangs that traffic the migrants have pocketed around 16 billion euros. Fences, police, monitoring systems and guns, are only some of the methods used to stop this flow. In 2014 some 600,000 people tried to enter the continent.
60 millon people left their country in 2014. To put it another way, one in every 122 people on Earth is a refugee. Let that sink in.
