The Trump Motto is waste as much money as necessary on enforcement of control because it superficially feels good to the enforcers and seems right to insecure leadership.
It costs more for enforcement than any waste, fraud and abuse of social systems. Boasting the amount of money saved does not account for the outrageous neurotic bureaucracy.
Signage is the last thing to change in good governance. Federal signage under Trump is being used for propaganda not substance.
