Consider to be electable for Parliament in Thailand you must have a college education. Only 2% of the people have that.

as pointed out Thailand is strickly governed by "classism" as you call it. It is based on thai buddhism, which does directly evolve from earlier hinduism.
See Ankor Wat, one of the mysteries of modern man.
It has become accepted that it fell apart in months (not years) due to rape and pillage of the surrounds. Trees were stripped, water ran out, everyone left.

Raped of the natural resources it fell in a day, like Easter Island.

Back in this time Siam (Thailand) Myanmar(Burma) and Cambodia were basically identical kingdoms under rule from an elite bloodline of kings.

The interesting thing is classism becomes an endemic part of even a modern asian society.

It is thought that in Ankor the peasants/workers, although under a king or deity, were housed and fed within the amazing structures we see today. It may have been a genre of socialism that worked (don't shoot me yet, I mean evidence suggests that it may have worked well for 600-100 years).

Anyone who has been to Ankor will have considered this.

In modern Bangkok people are educated (perhaps not the fact over the whole country) but they are still victim to higher forces, and wealth may have dictated godly power, to this day.

These PAD protests are a recent version of 30yrs of an educated middle class, who is still loyal to the patriarch, but also free thinking.

The sad part is that corrupt money is driving a wedge between a beautiful culture of acceptance and a time when people descibed as activists are actually normal people moving with the times.

Thais are the most proud people on earth. They love their kingdom and state religion.
What these protests are showing us is how far elitist forces will manipulate a situation for their own means.

The man behind it is a chinese thai, who got outrageously wealthy as a business man and politician by using this knowledge against his prolateriat and purely for his financial gain.
