Sure. Exactly the point I would make.

"An African with teaching credentials will likely do a better job teaching English to Chinese students than a U.S. citizen FT who graduated with a degree in economics, worked for two years at Starbucks who knows the meaning of twirking and barista but is unable to identify a gerund".

Not right at all because the African will have inferior teaching credentials all be them legally accepted. You have too much faith in your average African degree-holder and not enough in your streetwise American, who will no doubt impress the young Chinese students enough for them to listen to all his twirking tales(wotever twerking is when it's at home)
