EG, I know for sure that many Westerners can do much better in China than work for EF or other training centres or even private schools, for that matter. But that's not to say that all public sector employers here are superior. There is the occasionsl rogue employer among them!
Unfortunately, the good work that you and other regulars are doing on here by pointing out how bad many private sector employers can be does not prevent them from recruiting Western staff. These days Chinese employers in the field of education are swamped with job applications from reasonably well-qualified jobless Westerners. As it happens, I'm from the UK, and I'm a foreign teacher of English in China. My country is in recession, and things won't improve there fast. I think the UK is not a good country to live in. I'm glad to be in China, and I think there are others here like me who feel badly let down by the way their homelands are governed.
Even though EF is a lousy employer in China, it's much better to be employed by them than have to join a long dole queue in the UK. That said, I've taught in China for a number of years, and have never had to work for the likes of EF. But I may have been lucky not to have had to do so, or perhaps more likely, I've managed to avoid doing so because I will take teaching jobs well off the beaten track here, as I can do without Western goods and big Macs, etc. The link below is about the present economic situation in the UK, very enlightening and worth listening to:
