So you advocate selling books to foreigners on the 1975-1979 era, when most of them were not born, and children begging in bars and not going to school because their parents find this method a means of survival more profitable, because that is what is happening.
It's like the milk scams where the Cambodian woman approaches you and says she doesn't want money but could I buy her milk powder for her baby, they rent these babies, they are not even their babies, and as soon as you walk away, they are selling the milk powder back to the shops.
They need to get educated, get to school and build up Cambodia, not sit on the floor saying' Poor old me '
It's that kind of thinking holding them back.
Sure, it's not easy, but you have to start somewhere.
