Central banks in other countries should consider themselves really lucky that they do not have to deal with politicians like Ron Paul (and his son Rand Paul). Moreover, they do not have as troubled a central bank history or have higher number of scholars polishing their central bank history.
Central bankers in other countries can keep politicians quiet by just showing off their US university pedigree. It is just so easy really. But these games do not work on US politicians as most themselves come from such univs. The grilling a Fed official goes through is way higher than what central bankers go through in other countries. In latter, there is no grilling really.
Here is Rand Paul writing on why he thinks Fed should be audited more thoroughly.
