Since, it was abolished, slavery seems to have resurged recently when African or arabs pedigree in the modern maghreb started to sell Africans as slaves. The above clip can give you an inkling on what is now going on while the world, especially the so-called international community has kept mum simply because modern slaves are sold, restricted and sometimes die in the maghreb instead of crossing over to Europe. This is good for the holy europe that should not be invaded and disturbed by Black creatures.
Many Africans are not fleeing conflicts and poverty in their countries which have Europe's hallmarks. Many African countries, mainly those endowed with resources, are facing violent conflict in which warlords start war so as to have control on resources they sell to the West.
When it comes to poverty, bad governance, corruption and dependency, among others, are to blame. Many African countries are ruled by corrupt and inept regimes whose goals in power is exploiting their countries for narrow and personal gains. Interestingly, such rulers are supported by the same Europe and the west in general to see to it that they are perpetually colonised for the interests of Europe. The story is very complicated and long. Again, why have Africans always been welcoming their torturers? What would have been the reaction of the world had Africans sold their modern slave masters in the maghreb? Sheer hypocrisy and racism.
