It's a dirty job but someone has to do it.
Jews are over-represented in high profile positions because the jobs need to be done and there aren't enough qualified gentiles to fill them.
Amazing, isn't it? You guys make up 98% of the population and you still can't crank out enough high quality lawyers, doctors, administrators, and leaders to fill the really important positions. We end up in charge because those positions would otherwise go unfilled. We're not stealing jobs from you; we're doing what needs to be done because you lack the qualified personnel to do the job correctly yourselves.
So the question isn't “why are Jews so successful?” It's “why are gentiles so unsuccessful?” And the answer is:
That's the way you like it.
You enjoy mistreating each other. Gentile society is based on the predatory exploitation of the weak by the strong, the poor by the rich. Every gentile kisses the ass of those above him in the hierarchy, shits on the ones below.
Gentiles are extraordinarily wasteful of their human resources. Young people are allowed, even encouraged, to destroy their lives so as to serve as reminders to others of the consequences of nonconformity. You write off huge swaths of your society because of the color of their skin or the shape of their noses. Want to know why the Attorney General of the US is Jewish? It's because the black guy who would otherwise hold that position had his brains blown out as a teenager by an over-eager cop at a traffic stop. Why is the head of the CDC Jewish? Because the gentile who should have gone to med school and filled the role blew himself up making meth in his parents’ basement since higher education was never an option.
In Jewish society, beggars and the homeless are seen as a shanda, a shame, an issue to be addressed and alleviated. In gentile society, they are seen as a salutory example, a reminder to middle and working class wage slaves of what will happen to them if they don't keep their shoulders to the wheel and their noses to the grindstone. Poverty is a feature of gentile society, not a bug.
You like this. You enjoy watching other people suffer. Why else the malicious glee in tormenting the poor, making them jump through hoops for a pittance? Why else the relentless war on women, the vicious attacks on refugees? This is how it's done, how it's always been done. Gentiles eat their own.
Jews can't afford to be so profligate with their people's lives. There just aren't enough of us. Every Jewish life is cherished, every potential is nurtured and realized. Not only do we take care of our gifted, we take care of our ungifted as well. No one is left behind.
You just can't wrap your head around that, can you? This simply isn't how it's done and there must be some outside force, some unfair advantage that gives us our edge. The problem couldn't possibly be you.
The problem is you.
