To some extent the high-low vs middle idea applies to racial analyses. Some elite Jews (but also Anglos) have used coloured lower class immigration to break up the white "WASP" middle class. Where I think your conception of things goes wrong is making this solely a race based conspiracy. I prefer the Saker's conception of an "Anglo-Zionist Empire", This perspective of an "empire" fits well in reactionary thinking, while the Anglo-Zionist element works even with guys like David Duke who worked out their worldview alongside people like Alexander Solzhenitsyn.

So, yes, some elite Jews have been and are problematic, but its not unique to them and they aren't always the biggest issue. That side of things should be subordinated to the problem of out betrayal by our elites in general.
