What a distressing read; especially the posts from people, life myself, who have lived in Thailand for 10+ years and have been visiting Thailand for more than 50 years.
Nothing changes, as the rich and powerful will ensure that any changes which do take place will not disadvantage them in any way.
I recently read an academic article by two Thai academics about "contract farmers" and a powerful agribusiness company. The company concerned pressured Thai law makers to "weaken" the draft law on the rights of the contract farmers; when they only partially succeeded in weakening the law, the company then pressured the relevant government department to not enforce the new laws. Result - farmers' poverty increased, the company got richer. TIT.
Of course, the company cannot be named, due to Thai defamation laws (which contravene the "Western" understanding of "defamation").
Want to change the system? Learn from the experiences of the Move Forward Party and the Future Forward Party - if you are lucky, you have a warning to stop pushing for change, if not, then there is time in prison, and, if that does not change your attitude, finally death (sorry, I mean you disappear).
When the cancers of corruption and cronyism extend from the top to the bottom of a society, there is no treatment, no cure, only a slow painful death.
