That's $118,750,000,000.00 dollars a year, or
$325,342,400.00 per day, or
$13,555,933.00 per hour.
There are 301,621,157 Americans (according to the census estimates, 2008)
So then, if everyone in this country contributed equally to the tax burden,(which we all know is not the case, less than 50% of Americans pay any federal income taxes) then your personal contribution to the war would be about $3,200.00 so far.
Just for fun, can you think of anything better to do with $13.5 million/hour?
