Because it doesn't seem to.
That's not an answer. To me the video clearly shows these migrants choosing to illegally migrate (and fraudulently claim asylum in order to be able to stay) in order to make more money, not because of any persecution.
And anyway, it's irrelevant, because you did not distinguish between those in need and those not in need.
Vast majority are economic migrants. But of course, the pro-migrant European press refers to them all as "refugees".
Kind of like how Oscar the fake asylum seeker is being referred to as a "refugee" even though his mother admits he only wanted to make more money in the US.
