I'm aware of the Marshall plan. Parent's comment could have been read as "continues to fund the EU" which I don't think is a thing other than the usual, trade, etc.

Thanks for sharing the link to the ECSC, it's been a while since I read about that. I wouldn't say though that the US founded the EU (https://en.wikipedia.org/wiki/European_Union), at least not in the literal sense of the word.
