I think it's a combination of "everyone knows they're doing this stuff" and "the ones who could do something about it (i.e. charge/prosecute, change laws, etc.) are implicated".

Much like the problem in the US Congress: they are not subject to insider trading laws, so they can make huge sums of money acting on non-public information. The only people that can change that are ... members of the US Congress.
