That sounds really weird, like a rehashed mix of old style eugenics.
By the way, the worst problems with inbreeding are either in royal families, or in countries that condone cousin marriages. As you can see from this map, it is not Europe that takes the top spots in consanguinity.

Europe is one of the continent with the lowest actual inbreeding rate contrarily to Africa, the ‘new blood’ you seem to cherish. Could you, who is so clever compared to the stupid xenophobes, explain something to me? I am very curious about me how the crack dealing migrants from Mali and Niger that regularly vandalise my street will rejuvenate our economy?
Also it seems that in your indisputable intellectual superiority you seemed to forgot something rather… basic: that a country may not just be an economy?
The lack of imagination that comes from forcing everyone to eat pop culture for breakfast in this Eurovision mentality also limits innovation.
Small minded belief in the boxes and categories and a refusal to consider new possibilities is a real limitation in much of Europe that money cannot help us get over.
We’ve become a weak inbred continent incapable of competing on the world class level that our grandparents did in so many fields.
Europe thirsts for new blood, even if some of its less clever locals think otherwise
