overhead

Borrowing from Bastiat and "That Which is Seen and That Which is Unseen" . . . we know that every dollar the government spends is balanced by the dollar it takes from the public and thus is not spent by the public.

...the State gives poor excuse when it says, "With these hundred sous, we shall employ workmen."

The taxpayer can truthfully reply, "With the hundred sous, I would employ them myself." 

The claimed encouragement of labor is a delusion.

My question is: does anyone know the average cost of government overhead?  For every dollar it takes in, how much is spent on overhead that is not spent on the final deliverable?

If they spend $1T they take from the public, how much do they actually have to take to get that $1T?

If they have an overhead of just 10% (a ridiculously low estimate, I would guess), wouldn't they actually have to take $1.1T from our pockets to spend that Trillion?

Or should we figure it the other way: they take $1T from us but really only $0.9T is spent on "stimulus" spending and the other 10% is taken up by overhead?
