Interesting take. No doubt that Thailand's weather is way better than the one in Canada, Poland or Ireland where I had a chance to live. Should I have a choice though, I'd still say that mediterranean weather would be more pleasant to live.
Overall I've spent in Thailand around two years, but never had a feeling it's a never-ending holiday. It could be with a passive income or after winning a lottery, but those who have to work for their money won't agree I guess. Locals are another story though - when you manage them, they seem to be on permanent holidays ;-).
Spot on when it comes to cost of living especially in Bangkok and some touristy areas. While it's possible to live for around $1,000, it's also possible to spend $10,000 per month. It all depends what are you into.
Thai people are nice and smiley, but it's good to remember that smile expresses all kinds of emotions here. I find people in Cambodia friendlier than here with better understanding of foreign languages (English, French). Myanmar people are way friendlier than Thai...
I guess it all depends on individual's perspective, where else did you live and for how long. I'm glad you put a question mark at the end of your title. Statement without comparison to other countries in the region would have been pretty bold. ;-)
Good piece of writing though. Keep it up!
