You should do more Googling.

There were two waves of Jewish immigration. The first was strikingly wealthy. For example, in the South before the Civil War, the 1860 census showed the total number of US slaveholders was 393,964, which was “3.2 percent of the total Southern population” according to Keven C. Julius in The Abolitionist Decade, 1829–1838. The South’s Jewish population was only 20,000, but “about 5,000 Jews owned one or more slaves” according to Junius Rodrigues in The Historical Encyclopedia of World Slavery.

The second wave of Jewish immigration was more mixed, but you must remember that immigrants are usually people who have some wealth.

If you doubt that Jews are the wealthiest religious group: https://www.pewresearch.org/fact-tank/2016/10/11/how-income-varies-among-u-s-religious-groups/

Again, the fact that rich groups stay rich has nothing to do with the members of the groups. It has to do with class mobility under capitalism. Only antisemites blame Jews for their economic privilege — that’s why socialists call antisemitism the socialism of fools.
