More responsibility more money

A society,having no classes , is not a society. Like a house, it needs different structure in order to strengthen it. Hobbes says,"Human by nature are selfish and ambitious". In the other word , they are  greedy. The three classes ,mentioned in Plato' s republic fascinate the proclivity in human. By getting what they deserve, citizens as a whole contribute salutary effects to their society. Being rich or poor force mankind to expect the life of being affluent. Suppose , wealth is distributed evenly among them.,here is a question to concern: are there enough money to assist them in maintaining their responsibility?
