You could get rid of 10-25% of all of the Department of Redundancy Departments in the DC area employees by ordering a drug test of all employees.

Find some of your favorite worthless cost agencies. According to Fullerton.edu there are no less than 438 of them. I bet they missed more than a few. I'll also bet the Department of Useless Information and the Department of Silly Questions actually exist somewhere in the maze that is the us gooberment. Just think of the warehouse in Indiana Jones.
Somewhere under this veil are a raft of commissions like one of my favorites, The Navajo-Hopi Relocation Commission not to be confused with the Navajo-Hopi Lands Commission. Just his one little commission has 18 employees beavering away still relocatin' Navajo Joe and Harry Hopi from one place to another for the last 49 years at the cost of only $18 million a year and increasing no doubt.
There is no telling what this report, begun sometime during the Trump Administration and finally issued in 2023? actually cost or what it says: https://www.doioig.gov/sites/default/files/2021-migration/ONHIR%20Review_Status%20of%20ONHIR%20Tribal%20Consultation%20Process%20and%20Activities_Public.pdf

In just one week of review of this list I bet I could cut out half the government and nobody but those cut would know the difference.
One could spend a lifetime and still not finish studies of the usefulness and necessity of all the agencies. It would be much more effective to just wipe out all but the most obvious ones and let God sort it out.
