Wouldn't this likely mean US is much better than other countries to hide such scandals? E.g. maybe because they spend more money on it?

It could also mean that US media cares less about this than Israel media ([1]). Maybe Israel media has significantly more investigative-journalist manpower than US media. This way we, US citizens, would have fewer people researching such scandals.

[1] EDIT: By "cares less" I meant, as in, US media finds such stories less profitable and thus deprioritizes.
