The American consumer market is larger than the EU and China's combined (en.wikipedia.org)

That's a pretty bold claim. Seemingly by adding some numbers without explanation. Since you didn't bother to explain why you think you can draw that conclusion from those numbers, I won't bother to do the opposite.

According to that table, it's larger than the EU and China and India combined (with the leftover enough to include Belgium as well).

Nominally. Corrected for purchasing power, it’s only approximately 50% higher than either of them.
