Do we need rich people and poor people?

In a way do we need separation of class and income?

The idea of everyone being on the same level of standard of living and income, equal opportunity seems mostly a pipe dream. In a way it is needed the gaps…Could you imagine no one doing low income jobs?

Essentially it seems we need poor, middle and upper to maintain a sense of balance to the world. We need a foundation of the lower to properly facilitate everyone on top.
