Arthur, I find these concepts hard to understand in a country where so many people are starving and suffer from lack of health care. I think there are two sets of moral values in the Philippines, one for the rich and one for the poor.
I admit that my experience is meagre in the Philippines, but I have seen nothing that encourages me to think otherwise. Crime is truly outrageous. Government officials treat poor people like ****. doctors and lawyers lie and sell quack medication - or kick sick people onto the streets. Prostitution and rape are common, but asking for a divorce from a man who left you for another woman is considered morally wrong.
Ask for a divorce? You are a bad woman! Ask for money? How immoral! Get sick? A potential scam!
I do not want to offend the many Filipinos out there, because very one I have met has been lovely, decent, and honest. But lets not be blind to the bad things in society over there, and lets NOT impose middle class values on poor people.
