I think it's mainly capability. I know an SEC lawyer; he's successfully prosecuted a number of insider training cases, but thinks the SEC doesn't have the resources to take on really big players if they put up a fight, because they can overwhelm the SEC with legions of top lawyers and stalling tactics that can make cases take forever. The IRS is the same way; they've been cut way back so they can't effectively fight wealthy cheaters, so they mainly audit poor people for claiming the earned income tax credit incorrectly; those are easy cases for them to bring. A lot of this is because the IRS and SEC have been gutted by Congress to benefit their wealthy contributors.
