@Kuvult: ujm did not say that children with Jewish names fare better in life than those with non-Jewish names.
He just pointed out that it is a positive change.
Yidden are less focused on integrating with the goyim, and more proud of our traditions. This is a beautiful thing. (Especially in light of the aforementioned Vayikra Rabba)
@Gadolhatorah: It has been part of Jewish tradition for centuries to give Yiddishe nicknames, as apposed to goyishe names.
