You're close, but the modern occult movement is very eclectic in nature, so there are a lot of people who perform rituals to manipulate energies without being involved in any kind of crime. Rather it's the illuminati, who recruit from the higher degrees of organizations like freemasonry (but not limited to it). There's a big overlap with judaism in that many 33rd degree masons are jews, but there are also many non-jews in the illuminati. Skull & Bones is an example of a non-jewish illuminati organization. And then there are elitist rabbis and other jews whose ideology is in line with that of the illuminati, but of whom I can't establish membership of any illuminati organization. But you're correct to note that the people at the highest levels of the conspiracy, such as the Rothschilds, call upon demons. To be more specific: they worship Satan.
