I can only offer my thoughts, observations and opinions like anyone else on this subject. But I believe the answer lies within history with respects to comparisons made between the Phillippines and Thailand. Thailand has never been conquered by any nation and there is a reason for this. They uphold a culture that has not been divided, polluted or watered down. A true believe in their own way of thinking, one that has stood the test of time. We may easily judge them, but we do not really understand their ways or what it would be like to be truly Thai. When it comes to push and shove, aren't they really a proud people who may in the end only possess this one last piece of cultural heritage. We can critise them based possibly on our own cultural models and historical events.
Even 1500 years ago when the Khmer people controlled the Thai land they did not control the essence of the Thai culture and their way of thinking. Over 1 million people in the North East Thailand still speak this non tonal language of the Khmer empire.
With respects to the Phillippines, the spainish in the 1500's took this country. First with the sword and then with the cross. Those European models at that time brought the catholic church and a new way of thinking to this land. In some way it seems to change a culture, to what extent I do not know.
If anything you must admire at some level the Thai culture and their way of thinking. It will always be hard for any country to resist a western influence, so in my mind they are just trying to be who they have always been. Keeping, and isolating themselves against the outside world, so it is not so surprising that they will tighten their strings as a westen style of thought is constantly invading their way of life. They at least have some motivation not to cut their kingdom up into tinny pieces and sell it off to the highest bidder, and even more given the western economical shortfalls. Just a thought.
