You could also say that those people in their twenties teaching English in Asia are also not enhancing their resume either, and are also putting their future at great risk. 20 to 40 year old age range is time to save money, work hard, and financially consolidate yourself, not to piss one's life away in China.

Well that I can agree on. Of course the GW's and China appeasers will comment on how they are making a difference, and how it is a "great opportunity". There are far greener pastures than China, both in terms of the environment and making money.
