Plato worries that in too many nations:

 "...riches and rich men are honored in the State." 

He has no problem with rich people receiving honors for great contributions, service or contributions in society, but rather for being lauded specifically for having money. 

How they use their money should determine whether they are honored, but this is only sometimes the case. If money is honorable simply because it is money, the world is certainly in a fallen state. 

Still, Plato sees wealth as a benefit to society and a good thing in general. He simply believes that it is a lesser priority than virtue and wisdom.

This concern dominated European philosophy and history for centuries. Tocqueville was amazed that the American founders shifted this viewpoint slightly. Americans, he noted, were prone to promote virtue, wisdom and wealth all as good things and teach their children to seek them all. This combined approach to successful and happy life was a great strength in early America.

Sometimes there is no need to debate between good things!
