If Thai have land to farming they dont need much money. Like my mother and father in law's. They only buy seasoning's, detergent,soap... etc. Everything else come from land and from nature. I think father in law havent use money in decade, all money what he get he give wife. He handle my Mrs rubber farm and all money from there give hes daughter, casoline for motor and for hes Kubota he buy on credit whitch mother in law pay once/month.
