> I think the USG spends over $900 Billion every year. Europe spends about 1/10th of that

Do you mean that the EU spends 1/10th that, rather than Europe? Because France, Germany and the UK all spend €100-150bn each in grants depending on how you set your definition, and that’s atop the EU’s grant money.

Just eyeballing the figures across different countries, it looks like the USG distributes approximately the same amount in grants per capita as the EU & UK. Certainly not a 90% diff.
