I have and will argue until the end of time that most Filipino teachers are under-paid. In the past five years I have worked with many Filipino teachers, and quite frankly, they work circles around the "white NES teacher". 15,000 Baht may be OK for a new teacher with no experience, but seasoned teachers are grossly underpaid at this rate. Filipino teachers are the core teachers especially for the lower to mid-level primary students. I believe that once in middle or high School, NES teachers can do better, especially with the pronunciation and fine tuning the grammar in IP programs.
