And Materialism as proposed by Marx has little resemblence to how actual societies outside of some extreme resource starved communities work, and there is literally a hundred years plus of literature that shows so. That you still stick to a long disproven theory and see "no flaw" in it should give you plenty of thought about how up to date your other ideas are.
And yes, Lenin's earlier works had very interested readers in the German state security aparatus at the time.
