But Norway has given $6.69 per citizen privately in tsunami relief (in addition to government aid), and the USA has given $0.41 per citizen privately.
I'm fairly certain those numbers aren't up to date. I think the announced amount of aid from private organizations in the US alone already adds up to more than that.
I don't know where you are getting your numbers, but they're wrong.
There are 293,027,571 (July 2004 est.) Americans, and President Bush has pledged at least $350 million, that's about 3 times your number right there.
