The people perpetuating this idiotic "war on drugs" very much deserve to be unemployed.
In many ways, feeling bad for them would be like feeling bad for an unemployed slave trader. They make their living by actively imprisoning and permanently damaging other human beings.
Well, those people wouldn't be jobless as there are (serious) drugs to fight: Heroin and cocaine. But, that would be against the imperial interests of the USA, one powerful agency in particular. [1] [2] [3] [4] [5]

The thing that is wrong is the DEA (and state and local police) justify their high salary and high headcount with the War on Drugs. The vast majority of busts on the WoD is from pot.

In pure weight of seizure, pot accounts for 90% of all drugs seized, and the vast majority is simple possession. It's fairly simple politics. If the demand for drug fighting just lost 90% of it's target, why do we need so many drug fighters? In terms of a real war, if an army just decimated 90% of it's enemy, it's time to send some troops back home.
I understand the pushback from officers, and I don't like seeing people lose their jobs, but throwing people in jail for a now highly tolerated substance isn't worth supporting those jobs. They've had that deal for 50 years now, that market is about over, but like anyone in that position, they will have to leave kicking and screaming.
