Hmm I wouldn’t give them top 1 and they ain’t even close to top 1 so who is top 1 the most influential group in the whole world ? Easily
-the Jews
They single handedly build Morden America
From animation to show/movies to science to politics pretty much everything
From the best to even the worst such as C(P)orn for an example.
Jews by far are the most influential group 18 century until now
