You would not find it easy to live on the bottom pay for ESL teaching, the high end would be more liveable but no real 'Extras 'in your life , i had mentioned Cambodia , but i suddenly thought of a friends son in Korea , friendly, gratefull people toward ESL teachers , pay is good and 'After hours 'mentoring pays excellently . Might pay to check out that avenue of escape from your present job .
Japan ? I just read a news flash on my motor racing site (?) they are not paying thier ESL teachers at this time , no reason given . Colin
