Even Bill Gates has had enough. 

“On the one hand you want to demonstrate generosity and take in refugees, but the more generous you are, the more word gets around about this - which in turn motivates more people to leave Africa.”

While Germany has been one of the pioneers of the open door policy, it cannot “take in the huge, massive number of people who are wanting to make their way to Europe.”

Thus Gates advised European nations to take action in order to make it “more difficult for Africans to reach the continent via the current transit routes.”
