The Thai people really respect their royal family. There are pictures of them in buildings like with English countries.

However, I'm not sure if the current royals are strong enough to stand against big pharma. The King is a bit of a twink/hedonist and there is probably lots of blackmail material on him. But then again, he has had many scandals and they just wash off. https://worldofbuzz.com/thailands-new-king-eccentric-playboy-even-spotted-crop-top/
