The Reducing Over-Classification Act of 2010 allows government agencies to pay cash awards to employees who accurately classify government documents consistently and avoid unnecessary over-classification of information that is not a threat to national security.
I mean seriously a law that says "we will pay you more money to not break other laws and do the job you were hired to do" speaks volumes about how messed up the US government is. Why not try something different, perhaps? Like, when a law is broken or a policy violated then the individual or people responsible are held accountable and administrative or punitive measures are taken. Clinton certainly won't do anything at all to fix that, and Trump only has a marginally higher likelihood (if only because both Republicans and Democrats hate him and will dig in like petulant children rather than work with him).
I really wish that it looked like there was a tenable solution to this, but it doesn't appear like anything will change meaningfully in any of our lifetimes.
