As a percentage of GDP alright. Now how about absolute numbers, because pretending that doesn't matter isn't particularly helpful, and feels like playing with numbers rather than dealing with reality.
Although I am not a Christian, the parable of the poor widows offering always resonated with me.
"Jesus sat down opposite the place where the offerings were put and watched the crowd putting their money into the temple treasury. Many rich people threw in large amounts. But a poor widow came and put in two very small copper coins, worth only a few cents.
Calling his disciples to him, Jesus said, “Truly I tell you, this poor widow has put more into the treasury than all the others. They all gave out of their wealth; but she, out of her poverty, put in everything—all she had to live on.”
I see that as different, it is first and foremost an American project, born from a conflict between superpowers. I don't think the same is true about global charity.
It was a conflict between Communism/Socialism and Capitalism on the world stage and the proxy wars were fought over those ideologies. Now that communism is mostly recognized as a dead end, I wonder if the world order will slowly re-align. Socialism is taking off with Gen Z(see Reddit) so maybe the next administration will be socialist with AOC, Warren and Bernie.
The US also spends less than the amount designated by the UN on foreign aid.
America also spent less than Germany in % of GDP in the World Health Organization funding.
