I'm well aware what it says on the graph, thanks. My point was, you lead with an edgy "Good luck without us" then that graph. You provided no context, nor did it appear to relate at all to the discussion.
You're right that it's not necessarily at the cost of, although it still implies that the EU is growing at a faster rate than the US (to remain at a constant % where the US falls behind).
If it's just the distribution of the value of the top 60 companies, it ignores the vast numbers of BILLION dollar companies (Mrd. is billion, which is fairly easy for a even a beginner to translate).
Regardless, this graph (showing only 60 companies from one market sector of which the majority are not EU or UK) was just taken completely out of context and dropped into the discussion as if it in ANY way shows that the EU will suffer without the UK post Brexit. It does not show that (even though that's true). If you're going to use graphics to support your arguments please at least keep them relevant.
