That's not true actually. Andy Hall, Wesley Barnes, and Johnathan Head are three foreigners who've been sued under this law. There are more but these are the most notable.
Shady foreigners come and do shady deals with shady people then get scammed and blame Thailand. Do things in a legit way and you won't have any issues.
I'm pretty sure the people working at a Muay Thai gym would easily beat down an out of shape 40+ year old who wears his hat sideways and talks tough on Facebook and then has to like his own post lmao.
And you obviously have no concept of a polite smile. What, you think that when Thai people smile at you it's because they're happy to see you? You think that when a cashier in the USA says "How are you today?" it's because they actually care how you are? Now you're bringing up political systems, future business predictions, and employee welfare? For what? To show you care? About who? The people you just said should never be trusted 100%? It's hilarious that you bring up lowly paid public employees in Thailand while also invoking Vietnam as some improvement. Have you ever lived there? Because I have.
After 15 years as an expat in East Asia I can 100% say that this comment proves that you are the loser in this equation. It shows you associate yourself with the lowest echelon of society and you only do that because you are among them.
