While it is true that you don’t typically have to bribe your postman to deliver the mail in the US, in many key ways America’s political and financial practices make it in absolute terms far more corrupt than the usual global South suspects. After all, the US economy is worth over $16 trillion a year, so in our corruption a lot more money changes hands.
1. Instead of having short, publicly-funded political campaigns with limited and/or free advertising (as a number of Western European countries do), the US has long political campaigns in which candidates are dunned big bucks for advertising. American politicians don’t represent “the people.” With a few honorable exceptions, they represent the the 1%. American democracy is being corrupted out of existence.
2. That politicians can be bribed to reduce regulation of industries like banking (what is called “regulatory capture”) means that they will be so bribed.
3. That the chief villains of the 2008 meltdown (from which 90% of Americans have not recovered) have not been prosecuted is itself a form of corruption.
