The truth isn't pretty, I could redpill you for hours on this, if I had spare time. I think this is very important to understand the root of the problem here because in this moment in time we are living in a civilization throughly infested with jewry. We don't have much chances if we ignore their nature.
To understand this, firsthand one has to understand three laws of behavioral genetics: (as described in )
1) First Law. All human behavioral traits are heritable.
2) Second Law. The effect of being raised in the same family is smaller than the effect of genes.
3) Third Law. A substantial portion of the variation in complex human behavioral traits is not accounted for by the effects of genes or families.
The 3rd point is pretty blackpill-ish, but its truth and the leftoids are always thinking of new ways to misrepresent it, and yet it persists because its truth. If one shuns this truth, his race dies. If one accepts this truth, he applied [positive] eugenics to his race and it thrives. 
Also it is useful that most if not all of behavioral traits can be modeled as bell curves with average value and dispersion, and these bell curve behave according to breeder's equation, which basically means that the average height of a child of two parents will be the average of their heights. Interesting traits to model in this way are intelligence (verbal & spatial), ethnocentrism, sociopathy.
One can say that jews are unique as a people, because their race is a product of rational selection that started in ancient times, though the part of this selection that really matters took "only" during the last ~1200 years. The ancient stages of this selection were driven by competitive pressure of being able to remember & observe the Torah (which btw contains literal instructions to keep the race pure, and the metaphorical instruction for the smartest to lead their tribe to conquer all others) and by jewish priesthood, who decided who is to become Jew after the mixed marriage. In this stage jews were selected by millenia for traits useful in subverting large host civilizations and profiteering off them, one can see this pattern unfolding in Babylon, Egypt, Rome, medieval Europe, and now in our modern western civilization.
The latest part of their selection which takes place in last 1200 years could be described as a Talmud-driven eugenics program. Talmud is a level-up from the Torah, the babylonian talmud contains ~4500 pages of dense text which mostly explains how to understand the Torah. It is known that jews who mastered Talmud well became rabbis, and were married with daughters of other rabbis (accordind to their talmudic skill) and to daughters of rich jews (see the glimpse of this tradition is being kept being practiced among the orthodox: ). The jews that failed their studies were unwelcome and drifted away from the religion. That, and the crushing collectivist nature of quahal/jewish ghettoes led to selecting for a concentrate of verbal intelligence + "jewishness". This can be modeled mathematically  and it can be shown that a population can evolve in several hundred years to have +1 standard deviation in some arbitrary behavioral trait. So, this happened and now we are dealing with the consequences...
Truth is, jews that matter - the ashkenazim - have average verbal IQ of ~120  and average spatial IQ of ~93, which gives average IQ of 112~115  and explains their overrepresentation in sciences (though some part of this overrepresentation also requires nepotism for complete explanation). The rest of the jews are lower IQ, so they don't matter much, that's also the reason for Israel's lower average IQ of ~94. I use jews and askenazim interchangeably hereafter.
>Ashkenzais are high IQ, because they have a education system that is biased for them
No, their high IQ is heritable and mostly genetic . That's the reason they suddenly become doctors and lawyers or at least journalists as second generation US immigrants, being children of mere carpenters and lowly workers. That's the reason they ascended our universities  It can be said that education system is biased for them because it teaches everything verbally these days, and jews have very high average verbal IQ.
>and they also have a strict family household similar to East Asians, where their kike parents focus primarily on education.
This is true for orthodox, less true for liberal jewry, still somewhat true. Here comes another unpleasant truth: it doesn't matter much, because education doesn't influence intelligence or personality much (or most of the other behavior traits for that matter). You either inherit intelligence and/or conscientiousness and/or ethnocentrism from your parents, or you don't. Also note that east asians are another subspecies of homo sapiens, bred to pass https://en.wikipedia.org/wiki/Imperial_examination
