It really depends whether you're looking for a cultural experience or to make money. If you're looking to get rich - Thailand should be the last country on your list, but you will have a lot of fun living here.
Those people who have worked in Thailand, Japan and Korea are almost unanimous in their verdict - You may have a nicer lifestyle in Thailand but in the money stakes, just about everywhere else is better.
There are many jobs in Thailand that pay between 20,000 and 30,000 baht a month. Teachers were earning that sort of money back in the early 90's. I know, I was one of them. Those people who claim that teaching salaries in Thailand haven't risen in almost 20 years could well have a point.
