as a resident of Pattaya I would like to point out that there is no more underage prostitution here then in any other city in the world. Yes there is a lot of prostitution, the economy is based on it ever since the US military started coming here, but underage prostitution is illegal here, same as most western countries.  In 5 years I have never seen children being sold and never been offered any. I have no doubt there is child prostitution here if you look hard enough as it is in every city in the world. I know that wont sell many newspapers in the west but thats the way it is.
