1. Why are they and their children going there?

They'll say Don't smuggle while corruption is worse than smuggling to Europe. After all, a very few Nigerian who smuggled to Europe twenty years ago are now the best sources of revenue and employment in Nigeria. Europe herself is the best continent in the world because her sons and daughters smuggled to Africa, America, Asia and Australia before. History has it that Japan smuggles to Europe to steal technology. Chinese did the same later. Except gold and oil-rich countries, most rich countries are rich through dubious means.

Though it is bad to have ill-gotten riches, this is the system of our time since government avoid religion.
