Congress writes the tax laws and allocates the budgets to agencies for specific purposes. People can go to jail if they spend that money on something which Congress didn’t authorize.
So don’t blame the agency for doing what they’re required to do, blame the people who make the rules. If your cable company does something you don’t like, do you blame the clerk in front of you or the CEO who sets policy?
"Department of Mission Creep, Pork-Barrel, Tax and Spend, continues to tax and spend as it endeavors to expand pork-barrel mission."
