I personally know the author, Jon Levine, in fact, I'm the guy that got him the "dead-end job" with my family's firm. He's a member of the "I have an Ivy League degree, I deserve a job" a set. Never mind his degree was in history and political science, he felt entitled to a prestigious, high paying job in the worse economy in 70 years.
After a 5 month job search without a callback, I stepped in, did a favor and got him an entry level position at a very small PR firm. This was not a "dead-end job", he was the first hire at a newly formed company, there was definitely an opportunity for him to grow his career in a highly lucrative field. But, being that he went to NYU and Columbia (notice the name dropping in the article), growth didn't come fast enough for him.
We accommodated him (time off, flexible hours) while he spent two months trying to find another job. When nothing stateside panned out, he gave us three days notice before leaving for China. It's been a very surreal day for me, I'm incredibly disappointed that he chose to criticize a job which he only gained through my action.
I don't know whether any of you should go to China, but hopefully I've given you a little perspective on why he did.
TL;DR: I know author, he couldn't hack it stateside, took China job as last restort, not as some enlightened life decision.
