Tom Woods gives a good argument here that exactly the opposite was more likely the case.
1. Very funny to see a Mises Institute guy chuckle at how crazy those LaRouchians are.
2. The fascism saving European civilization thing is a bit more pressing to me than the Rockefeller Foundation thing (hell, I've done research supported by Rockefeller Foundation money... if I was being groomed by the financial elite I apparently missed that memo).
But I do think Woods gave a good argument on the issue he was exploring. Yes, I know this is something of a backhanded compliment, although the "compliment" part is as genuine as the backhand.
