I learned about the "LaRouche movement" when I was living in Dresden. The BüSo is his party in Germany. They are like a sect that will die when LaRouche and his wife resign.
They are in my opinion nuts and I wouldn´t give sh** on what they say. I once spoke with one of their followers at their booth in the citycenter. They were promoting one of the big-promise-project LaRouche talked about (I think they modified it now, but still the same nonsense), the Eurasian bridge, a project where they wanted to invest billions over billiosn to build high speed tracks from Vladivostok till Lisboa. When I asked how they want to pay for it, she said "We will print the money"
Also have a really simplistic approach to reality. To me LaRouche is a boulevard politian and Guru that makes money by selling endtime scenarios (and sometimes that sells like hit cake).
But yeah, make up your own mind.
