Not a true statement at all IMO..
Thailand does not have the same level of moral stigma associated with this kind of hospitality work.. I read soem acedemic papers (buggered if I have em linked) that discussed stigma and social roles, how it would effect future lives, how it would effect marriages, how much stigma there is.
The upshot of it was that being involved in the thai sex trades was percieved as not such a bad thing, and that it was a possible gateway out of the poverty via finding a rich man to be thier mistress (remember being a mia noi to a powerful man is a form of status here) or at least oving up the social ladder. Here in Thailand there is more stigma to being poor than there is to being an ex hooker.
As a western view we see that poverty is something that can be overcome and our dignity or morals are more important than the poverty, this society is only coming out of a feudal and fairly rigid caste system where people didnt change thier position in life easily.
How would I feel personally ?? Well I dont for one second think I would be happy about it.. However if the only options that I was able to provide for my offspring were between bar life, which with all of its problems does have some benefits, and the kind of grinding poverty that upcountry poor go through, a life of living in dirt and working 12 hour shifts for what a BG may make in 2 days for thier month, the option that perhaps the girl would find someone not too terrible to settle with, etc.. Well its a cold world and I dont know how much I would try to stop her.
Of course no father wants to think of his daughter working on her back, but (not being a father) I dont want to see my daughter up to her knees in a rice paddy for 100 baht a day, or slaving in a sweatshop either. Maybe my moral yardstick is a bit bent, that I can perhaps agree with, but looked at from purely lifestyle choices, and possible outcomes, escaping the poverty and changing thier life would be my desires.
