alt Hacker NewsThe most powerful men in the world do not loiter in city centres, which is what the commenter is referring to. It is a common phenomenon across Europe, readily observable, that groups of young men, commonly (but not exclusively) foreign, loiter in loose groups in town and city centres, where they appear to be doing... nothing.
I think the commenter has expanded further on what he or she thinks they ARE doing, I reserve judgement - but this phenomenon is apparent.
That is completely true and fascinates me. If you go to any city centre, train station, etc. in Europe, you will find lots of black people just... doing nothing. They are just there, sitting, perhaps alone, perhaps many of them. They aren't even talking or doing anything, they just stare into the distance. They are part of the scenery. I have no idea what this means, who brought them here, what they actually do (if anything), and who's going to take them away (and when).
