such low pay, unless they are under qualified or don't have much ambition to succeed.
There are many reasons that TEFL teachers go overseas - I'm sure you could work it out if you wanted to.
Those who are academically minded need to go overseas for the experience and research. Then others are doing so as a uni gap year etc. Then there are others like myself who were married, and wanted a lifestyle change from the hard drinking culture in geological servicing.
Then there are others who you are patronisingly referring to, who find themselves a vocation. If they can't hack it, they don't stay around for long.
One of my pals, an American, is an absolute wizard in the classroom, with his energy, command, and methodology. Parents attempt to insist that he takes their children into his classes.
He is a fantastic teacher you see. They do exist, though you seem to deride the profession
This guy is 70 and his eyes shine when he tells me what happened in his classes that morning.
Weird ( as I teach tech, not kids) but horses for courses...
What's your million dollar per annum profession Joker?
