You could say it's as good of a time or it's as bad of a time. However, though China in general wouldn't have changed in the way it treats foreigners, the schools now have the upper hand because of the influx of recruits and many may think they can get away with more because of this. Some posters have talked of schools bringing in batches of recruits with the deliberate intention of weeding out a potion of them and leaving them stranded. I don't know the truth of that, but that would be a change definitely for the worse.

It's probably also undeniable that there is much more competition for the better jobs, and thus one is more likely to end up in one of the less desirable jobs.

The framework of how business owners treat foreigners doesn't need to change for there to be a substantial negative impact as a consequence of many more new teachers; bosses can now just take advantage of opportunities they didn't have in the past, or couldn't get away with. Their attitudes don't need to change. All that needs to change is a tipping in the power ration so that they have more power, in which case they will take advantage of it. Thus, the would be teacher is at a greater disadvantage.
