What’s wrong with a heart of copper ?

According to Plato , the greek philospher , there are three kinds of people . Men with a heart of gold , men with a heart of silver and men with a heart of copper .

The men with a heart of gold are rational , supremely intelligent and hence fit to be rulers . Everyone in the society should aspire to be like them .On the other end of the scale are the men of copper .These people are guided by their desires and are not very rational . Hence a liability to the society .

Plato gave these ideas thousands of years ago yet they stand true even for today’s time . Today these men of gold are the ones who are rich or are politically powerful. And we are supposed to emulate them . The moment a kid graduates out of high school , he or she is supposed to get to a great college ,then get a great job, get rich or powerful .

This is the only way to lead a good life . But I wonder sometimes , why do I have to get that million dollar job or be a powerful buisnessman ? Why can I just be a blogger or a dancer ? What am I supposed to do with all this power and money . It might give some people happiness but that can’t be universally true !

I will be absolutely content with a small house , couple of friends and a peaceful life . Why is it so wrong to not want to conquer the world ? Why is it so wrong to follow your heart’s desire ? why is it so wrong to have a heart of copper ?
