I have friends in Germany, who constantly send me crap like this. I always have to remind them that, while Europe makes a lot of noise and gets a lot of attention, their entire National economies are smaller than any one of our top ten cities.
I get the jist of your statement, but it's just a bit inaccurate...
2023 numbers
#1 NY: $2.299T (New York-Newark, NY-NJ-CT-PA Combined Statistical Area)
... just NY, for a bit better accuracy: $1.286T
#10 Seattle: $0.518T (Seattle-Tacoma-Bellevue)
Three European countries beat NY greater metro area:
France: $3.049T
UK: $3.332T
Germany: $4.430T
Spain, Russia, Italy all beat NYC when not considering the part of the metro area which isn't actually NYC, which is a more valid comparison for this.
I couldn't find a just-Seattle figure in the brief time I bothered looking for it, but Norway, Austria, Ireland, Sweden, Belgium, Poland, Switzerland, Netherlands, and Turkey also beat Seattle metro GDP (edit: Seattle may be $0.487T of that $0.518T, unclear but stands to reason).
