I have heard this criticism before, that most western FT's are self-serving. It is true that many are recent college grads and are primarily looking to have a good time in a foreign country, and are therefore not overtly conscientious but it is also true that many schools, particularly private schools are for profit entities run by business people (not educators) looking to cash in on the lucrative English demand. Unfortunately, this tends to attract unscrupulous individuals who do not honor agreements and often willfully perpetrate wrongs against said teachers in order to maximize their profits. That is why the most frequent complaints from FT's are that their contract has not been honored and they are having problems with getting shorted on their pay. To say that someone who flew half way around the world under a certain agreement is selfish when that agreement has not been honored is reversing the actual case; the boss is selfish and using that individual anyway the please for their own ends. This is why people at public schools often have more positive things to say--they are working with educators who are not guided by a profit motive and under the auspices of a goverment organization, hence their agreements are met and their pay is not subject to the sneaky designs of an unscrupulous business person. What I think is sad is that working for these shady private school bosses often jades someone toward the culture, when every culture has shady, untrustworthy people as well as good, honorable people. Any time there is an unregulated industry where large profits can be quickly made, it tends to attract some who will misuse their situation, especially if they have someone at their legal mercy, the way FT's are and migrant workers are in the US. I've gone public school and I am never going back.
