Why Hoover is considered a do-nothing

In this excerpt from my interview with historian David Kennedy, I asked him to discuss the standard view that Hoover's ideology tied his hands and kept him from attacking the Great Depression while Roosevelt was an economic wizard. In his answer, Kennedy discusses how activist Hoover was, though ineffective.

Here, I ask Kennedy why Hoover has the reputation as a do-nothing guy, despite his attempts at intervention. Kennedy's answer is revealing.
