On the media and other industries they are said to control:

-"J. J. Goldberg, editorial director of the newspaper The Forward, in 1997 published a study of this myth regarding the United States, concluding that, although Jews do hold many prominent positions in the U.S. media industry, they "do not make a high priority of Jewish concerns" and that Jewish Americans generally perceive the media as anti-Israel. Variants on this theme have focused on Hollywood, the press, and the music industry."

-Alan Dershowitz: "Many of these individuals are Jewish only in the sense that their parents or grandparents happen to be Jews. They do not live Jewish lives or support Jewish causes. They certainly do not conspire to exercise any sort of “Jewish control” over the areas in which they work. Indeed, many individual Jews who are in positions of authority are anti-Israel and critical of Jewish values. Others simply don’t care about these issues ... So let’s stop all this nonsense about Jewish control over the media and praise those individual Jews who, by dint of hard work and talent, have earned their place, as individuals, in so many areas of American life.", "Whenever there are allegations of Jewish “control” over the “media,” the primary examples cited are The New York Times and the Washington Post. Both were founded by families of Jewish origin. But neither has ever gone out of its way to promote Jewish causes or values. The New York Times was derelict in reporting on the Holocaust and generally opposed the establishment of Israel. It remains critical of many current Israeli policies (as does the Washington Post)."

-https://gab.com/Fonched/posts/106292117954739911m A collection of infographics (one denies Jews having a majority of executive positions at media companies, another breaks down the famed CNN meme and claims these graphs baselessly place Stars of David to inflate the totals). The "confirmation bias" portion refers to how an equal amount or more Whites may control institutions, seeing as how there may be significant numbers of Jewish coalitions supporting refugees, feminism but no count for multiple Christian groups doing the same.

On expulsions, the thread and its comments I have linked on the essentially sums up what the left has to say about these expulsions and why they happened, if they were impactful enough. They mostly boil these occurences down to them having been one of the only minorities around and therefore a scapegoat, religious persecution and not actual distaste over actions, allege that this pattern is untrue given countries existed that have been friendly to Jews for many years, or that other groups have been expelled to more deserving angles. Keep me informed if there's any part you are not sure about still.
