I agree with you. The issues involved seem way more complicated than either of our posts cover. Now I am wondering whether exchange student programs are all that useful in the long run, in terms of GDP or some other national metric. In terms of national testing averages, I don't see a quick answer to whether non-native speaking students affect the average at all.
