In Plato's republic (book II) Plato talks a lot about justice and its evils. Towards the end of the book plato also brings about the idea of a hypothetical perfect city. In this hypothetical city it must start out with only producer. People who can only benefit their societies by doing things such as farming or metal working. Plato describes this city as one of the purest and one of the most ideal places because in this city you wont have the desires of money, and lust for such artificial items. I disagree with Plato about this because in a city with no material or superficial awards, much of the population would loose its motivation to produce the best items that they are able to produce. Without rewards or motivations people will just causally produce their items, just to get by, and live as every other producer does in the city. In a civilization you need competitions to encourage people to do the best that they are capable of doing.
