that is a crazy video. You can either take her thesis at her word, or you can read between the lines and realize that this is an incredible outline of how government transfers wealth to the already wealthy. Her suggestion is that the reason why the US is such a dynamic economic system is because the government underwrites it; but this is a flawed concept. In the era 1860-1920 the US government did not underwrite very much scientific or technology or provide SBIRs or any such thing, and you would be hard pressed to argue that the US did not undergo major economic improvement.
