It doesn’t matter what percentage of a budget is what. If a government is corrupt to the point of absurdity, the spending is largely ineffective.
The tax dollars were captured and the value of what theyre being used for is siphoned by middlemen (insurance in health care, middlemen inflating prices in the military) and as a result the prices in both examples are no longer attached to reality.
The more corruption settles in, the less effective voting becomes. This is why the citizenry has civic duties beyond voting.
