I do not see why this is a bad thing for China, especially for China's academic and intellectual interest is concerned.
In regards to quality, I do agree that Chinese schools should enforce a more competitive standards board. You want the best of the best coming to your country to teach, after-all. This is how it happens in Japan. Western-teachers that come to Japan are selected rigorously and go through a series of battery tests that takes into consideration their maturity level, intellectual level (IQ), personality tests, level of education, and working understanding of the Japanese language as well as a positive reflection on Japan and Japanese society/ culture. All others that don't make the cut are not selected.
White trash like that are the very reasons why Japan should never allow low quality professionals into the country. Secondly, that Blanc individual was not an academian, and he entered the country for purely insipid reasons. He should be ejected and classified persona non grata. This applies for all sex predators that try to take advantage of the Japanese Race.
I agree on all fronts, my friend.
China should re-define what is an expert/expat is. They should have higher standards and very strict enforcement of carefully-written laws.
For a start, nothing below a PhD and work experience (plus, maybe 30+ years age threshold) should be considered/employed/given work visa as an expert.
This criteria should include English teachers. Those schools that breach the law and employ low quality/unqualified persons should be heavily fined and, in case of a repeat of the crime, closed down.
I guess it has to do with development, however, as you climb up the ladder of economic development, you will have more stricter and higher benchmarks. Japan, as I learn from you, seems like such a case where laws are well-written and well-enforced.
I have shared in the past reports on China's own efforts to redefine the expert/teacher business and set up a more strict oversight. But, a state-society cooperation is still lacking in China, with greedy schools employing the White trash for the sake of easy bucks.
I am against to entirely closed down China's professional sectors to foreigners but standards must be really high. Besides, the persons must be closely monitored/tracked when they are in China. They may be enforced to report to local police station every month or something like this can be done, as a start.
English teaching, in the meantime, should not be considered an expert profession and completely closed down as an import sector.
The Western expat problem is not simply an issue in China, it is all over Asia. It has to do with the level of development. But this is not an excuse. The government should come out forcefully and without mercy.
