Apples and oranges indeed. In the first place if anyone posting here has suggested that Americans are not generous people I must have missed it. In the second place you make no allowances for population differences, although you were very quick to note that, for example, Canada has one tenth the population of the U.S. I am quite certain that many of the other counteries identified are at similar percentages. Now China with all our money and all its population could have done better.
