They probably arent. Some Jew/s at CNN probably noticed or were alerted that a group of goys had influence in a field they view as their personal fiefdom, economics, and so went after them in the typical Jewish manner. Using the media to attack them and accuse them of being "too white".

If some of them were Jewish I doubt this hit piece by a Jewish author would have ever been written. It's just exhibit number 489327832 of some ethnocentric Jews using ill gotten power and influence to attack whites. As for why this panel wasnt already dominated by Jews, maybe because the person the Jew author complains about being able to hand pick it actually believed in merit based appointments. Dont worry, Jews are onto him now and this will likely be "corrected".
