Simple...
Thailand: corruption, lack of safety, lack of protection and accountability, cheap
The West: a lot less corruption, far safer, a lot more protection and accountability, expensive
It's quite simply about the pros and cons of each. You cannot have a chilled out, cheap and fun society while following millions of strict laws and constantly stressing about everything you do. Equally, you cannot have a very functional society where rules are followed to the letter and strict standards are kept while having fun all the time.
As a foreigner, with foreign money and other benefits, you have a false idea of what Thailand is really like. You have a closer idea of what Thailand is like for the wealthy elite. If you had to live more like a regular Thai, were disabled, or were the victim of some sort of horrific crime or industrial accident, you would probably feel differently.
