Well, some of us actually have higher qualifications than that of a Bronze swimming certificate, you know? Sure, it can pay good money for a relatively easy job, but it probably isn't going to be a long term career option.

I could even guess that the poster was actually Chinese as they have made that all too common assumption/false allegation (that usually comes from 19 year old Chinese nationalist, male, teenage, W.O.W enthusiast virgins) that every English teacher is fleeing from unemployment or relative poverty in their home country. Mind you, this time, the poster was quite creative I must admit. Funeral Parlour? That's a far more imaginative choice of dead end job providing employer than McDonald's or a warehouse, well done. It makes for a beautiful story. Chinese people love to write beautiful stories.

Also, a lot of training centre bosses rake in a fair bit of business in the short term, but can fail in the long term. Both teachers and more importantly students/customers see through the flaws of the business model and the place fails, either due to a lack of repeat business or more likely being the case, legal troubles. Some lack in marketing ability, expand too fast, offer a poor product e.t.c too. Chinese authorities might often fail to protect teachers and get bribed by corrupt local TC bosses, but they tend not to react well when a centre fails to even bother getting the correct visa for their foreign teachers and so on.
