Poor men need not go up as rich men should come down. This statement is perfectly true. The poor will survive. Living a simple, real life, and working hard. They are happy with necessities which may not be expensive. They are content and that brings happiness. They do not have to worry about safeguarding the excess.
But the rich may not know how to live simply, just with basic necessities. They may have servants to do basic chores. They travel in style and sometimes for no reason. They spend unnecessarily. So the poor need not go up as much as the rich need to come down is true.
