2- The market for English runs into billions a year, so, while it doesn't mean that an English speaking company has an economic advantage, it is a serious economic player in it own right. You could also argue that other countries have to invest heavily in language, which is a cost they have to carry to compete, so there are weaknesses in this argument.
4- Demographic factors can be over-rated; it is of little importance which language is spoken is garment factories- the only language that matters is the one used for transactions between manufacturers and buyers, etc.
5- I'm not sure the rate can be predicted so confidently- the boom areas are probably examples of over-expansion.
9- Who is going to lay out the ethical framework? there is no representative body worth talking about- there are many bodies, but no international standards. Plus vast areas of the ESL masrket are bandit territory with no wish to cincern themselves with anything other than money. I think this is a topic that will be more discussed than actually put into effect.
The others, I broadly agree with.
