8k is a lot. I don't understand why people who have lots of money and good jobs like to tahriib. Why are they risking their lives if they already have enough money. If they can afford the expenses to do tahriib they can maybe open small business or something.
I have a feeling that their parents encourage them. They see other people's children giving them 'biil' and they want their children to do the same. I highly doubt this girl wanted to leave her kids without some sort of pressure.
