IMO, working for 'Buckie' and the like is much preferable to working for Chinese training centres. It's all a matter of degrees. I mean that I can envisage scenarios where literate western oldtimers with some bucks want to work in the public sector for a walk in the park, relatively speaking, but they haven't the necessary academic qualifications to get Z visas to do so legally. There will also be others who wanna buck China's suppressive visa regs, and can do so if they're adventurous enough, 'specially if they've a Chinese relative to 'use' to let them take the piss out of the lousy visa regs here. 'Buckie' is their vehicle to do same, but perhaps not the best one, though that situation is miles better than slaving for EF and the like.
