The supposed "superiority" of the Askenazi is a myth propagated by Jews who pretty much control the entire education network in the English speaking world ( UK, US, Canada, Australia, and the colonies )
In a capitalistic society, we can use a simple econometric model based on financial success of each ethnic group to better guage your supposed notion of ethnic superiority. The theory being that the smartest ethnic group will have the highest median generation of wealth. Some ethnic groups have been in the US longer than others, so historical accumulation would be a moot statistics.
Based on the simple premise above, we will find that the Indian-Americans ( ie from India, as opposed to the native-Indians) have the highest median per capita figure for income generation (

So in essence, based on a capitalistic metric, Jews are in fact not the most superior, since they've been here about as long as the Anglos and yet their median accumulation rate is lower than the Indian-Americans.
of course, the Jews who do these studies will never tell you their real findings. The real reasons why one ethnic group performs better than another, is NOT because of a higher intellect or some such nonesense. It is because of extraneous factors, the most important being the Mobility quotient. You will find both Jews and Indians have family relations who live in every corner of the world. This makes mobility easier for these groups to take advantage of superior economic environments anywhere. example, during the heydays of Argentina, a vast number of Jews migrated there. Once economic conditions in the US seemed to have better prospects, these jews were able to easily migrate to the US because of their familial ties in the US. Of course, then there is the increased mobility of capital within these groups. These groups are able to take advantage of economic booms sooner because their familial ties allow them to move capital around the globe quite easily and freely. I could go on, but I think my point has been made.
