People in the USA certainly can't understand financial poverty can exist without any food insecurity. Edible things are cheap and also grow on public land all over Cambodia. There is never a homeless person that can't pick a kilo mangoes or find a papaya.
The USA is a whole other story, people often with great financial wealth, but who live in food desserts and survive on canned and frozen foods while driving a BMW to work each day. The irony is not lost on me, I'd rather drive a tuk-tuk and eat like a king.
