You seem to somehow connect it to public spending. But "lost resources" happen in every kind of company and are just a function of size. A small office will lose some random notes, a data processing company will have a few TB hanging around due to forgotten cleanup processes. It just happens and one of the functions of your AWS TAM is to ask you sometimes about an unused bucket they noticed. The more you spend every month, the more things can become a rounding error in cost.
