You are correct in that other countries governments give more as a percentage of GDP. The reason I bring in the private funding is because you suggested that Americans don't do as much. That argument is either incorrect or needed to be clarified (if you meant simply in terms of tax dollars)
I am sure many are unhappy with how their tax dollars are distributed in terms of foreign aid. How much is going to Israel? vs. the rest of the world? Why does the US government need to be involved as much as it is when we do such a good job with private donations?
No I wasn't suggesting that Americans don't give much. I was suggesting they believe that our government gives more dollars in foreign aid than it does, and that they think we give too much.
