I think these are not the right questions to ask. The Rothschilds may be dying or losing significance or they may still be on top but this won't change the bigger picture.

My belief is that money Jews are secondary to the priestly class. The decisions at the very top are made by people of the likes of Menachem Mendel Schneerson. This priestly class may consult with the likes of Rothschilds but they operate on long set plans of the kind of the protocols of the elders of zion.

They have continuity. The same way the US government does not really change with presidential candidates. The Jews have created a secret state hierarchy long ago and still operate under it.

You have to think of Judaism core and heart as being the breeders (i.e. the orthodox Jews who do nothing but keep their Jewish core intact and supply numbers). Those orthodox Jews are not impressive in the least but without them Judaism would have long ended.
