Here's another random thought...Here's a random thought, what are the countries these folk are fleeing from doing to stop their citizens wanting to leave?
Most of those fleeing are doing so because of the historical colonialism and exploitation by the west...
Not to mention the illegal wars and artificial borders often imposed by western nations...
So given the inevitable poverty and unrest that occurs, the question is not 'what are they doing'...
It's how can they be expected to be able to afford preventing it happening!
Unless things are drastically changed, this is only going to get worse until we hit the tipping point....
And then all hell will be let loose!
