1/ They spent a lot of money to build Buddhist temples and grand structures. They are obsessed with it and believe it is a form of saving karma for the next life. It reminds me of the Pharaohs.
2/ They royals are literally gods and beyond reproach. We got a Thai native assigned to our group just to make sure we would not misbehave or something and our guide told us one of the most severe crimes that no one can bail us out from would be lese majeste. Stuff like don't point at the king picture and laugh or step on anything with his picture, including the money.
3/ Plenty of tourist traps, ranging from honey farms to homeopathic "institute". And lots of good street food.
