A City of Good...Communism?

The Republic Book II may be my favorite reading so far this semester.

In the Republic Book II - Socrates suggests a city created entirely of the bare necessities (food, clothes, health, shelter, etc..) and populate it with workers. Those workers will be important for the growing of the city, and the production of such necessities. Socrates then suggests that you would introduce the city to a "fever", poets, merchants, actors - who will have an surplus of income, leading to civil unrest, inequality, and essentially war. This is where I think of other ideology from political philosophers, such as Karl Marx. I know it may sound funny but hear me out...

Socrates is suggesting that a city with the bare necessities would be a good, just city...but once you introduce the fluctuation of income it will lead to inequality. Now, Marx suggests that by leveling all playing fields (income) and each person having the same benefits, society will be equal.

It seems as though Socrates was a leading front for Marx's argument on communism. From Socrates idea of a city of good, you can see that those workers who were first there would be the proletariats of the capitalist society, and the "feverish" people (actors, poets, merchants) would essentially be the bourgeois of the capitalist society.

When it all comes down to it, it seems that injustice/inequality/unrest is seen as more of an issue of class distinction.
