Income Classes

Do you think there should be any classes of income?

personal i think classes of income should not exist but with this arises a problem of no advancement, because there is nothing to work for.

but solving this i found a little thing about a visit from planet Iarga and there it must be one of the best places to live. and if you believe no aliens exist i will still tell you to go read this just to see the philosophy of how it works there. and if this guy thought this up he is a pretty good mind!!! just enter A visit from Iarga on Google and you will get the site where it is.

So what is your thoughts?
