As with most immigrant groups, one of the major things the Jewish community did to cope with discrimination was to become insular and to support one another. For this reason, they did things like forming mutual aid societies to help new immigrants or those who were struggling. They created Yiddish language newspapers. They had theater groups and vaudeville performers who did their acts in Yiddish.
In addition to this, Jews worked hard at becoming more educated. Jewish families would make sacrifices to ensure their children could do well in school. This was seen as an important way to try to allow their children to advance farther in society than the parents had been able to.
