In most countries across the world, tax payers money may go to defence, buying of equipments and arms for the defence of the country. Education, housing, hospitals , infrastructures, transport and others.
So how it was distributed, we really don't know, probably not necessary to know. If a very small percentage goes to providing free medical facilities for those age 81 and above. The amount may be just peanuts.
Surely tax payers won't mind. Ultimately, no mater where it goes, we still got to pay taxes.
