You can hardly blame someone for accepting huge speaking fees. While I do think that the revolving door of government and private industry is a problem, I think if we set the bar too high, then no one will ever be pure enough. How exactly would one find an experienced industry expert, especially in finance that hasn't at some point been highly paid by industry? We could go with lifetime politicians, I guess... or academics, but we all know how the people usually respond to those types of appointees. Are we to presume that these industry insiders were paying huge speaking fees to Janet Yellen just in case the 75 year old received another high profile political appointment? Do companies worry about hiring a CEO who used to work for a competitor? I just don't see a problem per se unless there is evidence of undue influence.
