Where are the Thais?

During Windup Girl, we're introduced to an American, a yellow-card, Chinese man, a sex slave, and Jaidee. While Jaidee is actually Thai, he is a great exception to the typical Thai described within the text. Do you think it is advantageous to the story line to show the point of view of so many people that are disadvantaged/unwanted? I personally think it would have been an interesting addition to include a native Thai, not like Kanya or Jaidee who have power, but an everyday person who is dealing with so many outside forces.
