I think the biggest scandal that isn't discussed often enough (in the US) is not spying on foreign government officials for legitimate security-related reasons (e.g. this), it is spying on foreign government officials to give the US an advantage in trade negotiations or worse passing on "tips" to US-based private companies so they can gain an advantage during negotiations/bidding.
The US constantly beats the capitalism drum, and that's fine. But it seem hypocritical to beat the capitalism drum with one hand, while with the other quietly subverting capitalism by giving certain favored entities tips and advantages.
Even people in the US should be asking why large US corporations are given these tips/advantages/etc while small-medium US businesses are not. Let alone the immorality of helping a US company win against a foreign one due to state supplied corporate espionage.
The justification "well China does it!!1!" while true, is just kind of pathetic. China does a lot of things, doesn't make it right for a country that claims it is the beacon is capitalism and democracy to do the same.
