How Rich are U ?

I recently bumped into this site called How Rich Are u .If you enter your annual income it will show where you belong w.r.t to rich and poor. I am not sure about the authenticity and credibility of the site ,but it is interesting to know where you are w.r.t other rich and poor. With my parltry salary i am in top 10% of the people , that means 90% of the people are poorer than me , Thats not what i am interested in. I am interested in how uneven the wealth is distributed in the capitalist market!!..

I hope one day there will be a free world where no money is involved but only services !!.Imagine a world where people just trade services , for e.g as a software developer i develop software to make things efficient and a contractor builds my house and car company builds a car for me!!. A happy world where all the people are equally rich and all jobs are treated equally.
