It's because they form a cohesive social group with no outside loyalties of higher priority, and antisemitism by the out-group is a normal social reaction. Yes, a normal social reaction. And to any future internet historian that might be reading this, before you jump my case and scream 'anti-semite'. I can guarantee you'll never guess who I stole this notion from: > The formation of groups has an invigorating effect in all spheres of human striving, perhaps mostly due to the struggle between the convictions and aims represented by the different groups. **The Jews too form such a group with a definite character of its own, and anti-Semitism is nothing but the antagonistic attitude produced in the non-Jews by the Jewish group. This is a normal social reaction.** -Albert Einstein [source](https://www.unz.com/print/Colliers-1938nov26-00009/?View=PDF) Unfortunately the article doesn't have rest of it, and some of it is bullshit, but it admits to some of the things they do. The simple answer is they talk to each other, favor each other, and nothing or no one else as much. Outside of earshot of the goyim (their word for the out-group) they'll collude, coordinate, and give each other preferential treatment, I'm sure. Every group does this with it's in group members. It's nothing different than 'locker room talk' among the guys. But the preferential behavior outside the locker room has significant real world consequences. But at it's heart, it's basically just nepotism combined with usury giving them power to economically dominate - and money is the most protean form of power - combined with thousands of years of doing it such that they never have to struggle, strive, or start from scratch because the behavior is older than the oldest living jew and they help each other out. Complete with loans to each other **without** charging interest. There's a reason both Christianity and Islam used to prohibit usury, and it's because it's fucking evil. It *punishes* hardship instead of becoming more lenient. Same reason jews don't do it to each other. They do evil to the outgroup, not to each other. If you took a 10,000 people of the full spectrum of us living on earth, including a representative sample of each took them naked to another planet, or all with just the same resources as each other, and denied them usury and other such financial shenanigans like money changing, I bet they wouldn't rise to power again, or if so it would be random. And if you conducted the same experiment 100 times, they would only a number of times commensurate with their population ratio. So in short, they're a very cohesive group with prodigiously already amassed wealth, and no loyalty higher than that of to each other, including superseding telling the truth or ethical behavior. Without that advantage and that behavior, they'd lose. I bet if you took any other group, gave them the same cohesiveness, same financial tricks, that group would end up in the traditional jewish role instead. That is to say, there's nothing innately special about them that makes them superior. And without the resources already amassed they would not be capable of the level of social domination that they currently hold. Mother nature requires balance right down to physics, and balance that pays for that power is the suffering of the working class to barely scrape by while a small fraction of the population thrives in orders of magnitude more power and comfort.
