I've just returned from a brief trip to Washington, where I attended a conference on taxes, technology, and privacy, and offered comments on a paper by Kyle Logue and Joel Slemrod on endowment taxation, the use by the tax system of genetic "tags" that correlate with expected income, etc.
While there, I happened to chat with several people who have worked for a long time in different agencies of the executive branch of the government (not just tax-related), and who report on what a historically unprecedented horror it is for career professionals in the government to have to deal with the current Bush Administration (earlier Republican Administrations were generally fine). Essentially, it's like being in the Soviet Union with a party commissar harassing everyone, except that while he can (and does) make your life miserable and prevent all honest governance he at least can't have you arrested.
Once the national nightmare has ended, someone should really go around collecting accounts from people in different departments. While unlikely to be a best-seller, it would be genuinely eye-opening reading with a lot of startling stories about dishonesty and dirty work.
