As someone outside the US who has to work with the FDA, Americans should be very proud of how thorough FDA inspectors are at auditing and how good they are at identifying non-conformances and just plain criminal lack of due diligence.
There is a database of 'offenders' that are no longer allowed to sell their products it's seriously scary what some companies/people are willing to do for a quick buck.
You could argue that in the US there is a considerable amount of lobbying and influence that defeats the impartiality of some federal bodies but overall they do an amazing job at keep everyone safe.
