I don't agree they are trying to overthrow the government, but they do use the government to advance their personal aims, including but not limited to financial and ideological goals.

The problem with these wealthy fools is the same as all similar fools throughout history.
Look no further than the Bleichroeders, Bismarks, Hohenstaufens, Warburgs and Rothschilds.
You cannot unharness the forces of ignorance, reaction (meaning in the old political sense) and religion in the name of your profits without becoming the arbitraty victims of them.
