I have no idea how those metrics are calcupated, but by selecting "international USD" (whatever that means...), the US and EU are basically on par... Seems almost like economics are too complex a topic to easily compare in an online comment.
GDP is actually the easiest, most apples-to-aples thing to compare, I don't know why you're saying it's too complex. And the graph clearly shows the EU falling behind the US, both in nominal $ and in GDP per capita.
