Bringing Children Up In Bangkok

I live in Bangkok with my Thai husband and my four month old baby. I have been here for 5 years and planned to make this my permanent home. However, since having my son I've started worrying about the effect living here might have on his education. I actually teach at an established International School in Bangkok where my son could go for free but I still worry that he'll end up speaking Thai English and never achieve native speaker fluency. Even the children at my school with two native English speaking parents often start speaking Thai English just so they fit in. I also worry about other aspects of his education - the fact few Thai people read, the fact television is generally mindless game shows and soap operas, the fact that it's still culturally acceptable to believe in ghosts, the fact that young people are still not taught to question - in my opinion it's just generally quite a non-thinking culture (please don't kill me!). I do absolutely love Thailand and would quite happily live here until I draw my last breath but I also think that the world here looks rosy from the vantage point that having been brought up in a western country elevates me to. My salary is 20 times more than that of a Thai trained teacher - does that mean I'm 20 times better - most definately not. If I'd been brought up in Thailand I've no doubt that I'd be out there slogging my guts out for 15,000 a month alongside millions of other Thais. Is that what the future holds for my son if we stay here? Even reading the pages here about Thai universities - the lecturers can't speak English, you can pay bribes to pass your degree. My life is a lot better here than it was back home but is Bangkok still smiley once you have children?
