I remember reading, maybe 10-15 years ago, that due to various factors, there would be massive migration from Africa northwards and that there would be fuck all we could do about it.
I wish I could remember the source, but it has proved to be spot on.
The trouble is that this is a complex problem, and people (generally) want simple solutions, delivered today. And get mighty frustrated when these simple solutions don't emerge.
However, I am going to offer one long-term suggestion for amelioration. Stop bombing the fuck out of third-world countries because we don't like their leaders.
