It is an unfortunate reality. I have no idea what the answer to the problem is. I do know that the majority of novels written about Thailand paint a fairly disturbing picture of the practices here. Novels such as Thai Girl, Private Dancer, Bangkok 8, and books like Bangkok Dick, Confessions of a Bangkok Private Eye. I can go on, but you get the point. Thai Girl probably best shows the extent of the problem here the best without sensationalising it. Andrew Hicks (the author) isn't always on the money, but he certainly has seen enough to make the read very interesting, and at times quite funny. With the exception of Thai girl, the novels mentioned here deal with the farang-thai issues, where Thai Girl addresses both thai-thai and thai-farang issues.
That said, Thais are very discreet. And the Thai practices are very muted comapred to what westerners do. It is a source of amusement for many thais to see a farang and a bar-girl walking down the street together. Thai men would never be seen in public with a prostitute, and if he were to be seen with one, he would have a major loss of face. The problem is not the amount of prostitution that is Thai-Thai prostitution, the problem is that a few farangs give Thai women a very bad name.
As far as changing it, that will take a very long time. The economy benefits from it. As the Thais become increasingly educated, the problem will slowly abate.
And whoever the goon was that referenced me, I made no mention (I think) of the number of Thais who visit prostitutes, what I said was that the vast majority of prostitution here is Thai-Thai. Simple math would prove that. Foriegners make up a small fraction of the population here, and the demand for commercial sex is a small fraction as well. Even if you skew the numbers, there is no way to arrive at any conclusion other than the vast majority of sex workers service the local population. Thailand is no different than any other country in that regard. I would like to see somebody do the math that would show the contrary!
BTW- The MAXIMUM sentence for sex with a person under 16 is 20 years. If the victim is under 13, the max is life.
There have been several high profile pedophilia cases as of late, and the sentence handed to each of the three perps was 10 years.
The minimum wage in Thailand is 4400 a month, or just under 1100 baht a week, not 200 baht per week. I am not sure what rice farmers make, but I am sure that even the smallest factories adhere to the minimum wage requirements.
