In a traditional society,production and consumption paUerns are governed by tradition:everyperson’S place within the economic system is fixed by parentage,religion and custom.     Transac—tions take place on the basis of tradition,too.People belonging to a certain group or caste mayhave an obligation to care for other persons,provide them with food and shelter,care for theirhealth,and provide for their education.Clearly,in a system where every decision is made on thebasis of tradition alone,progress may be difficult to achievE.A stagnant society may result.{TS}What is main purpose of the passage?
