Rich people need poor people. Otherwise they cannot be what they are.
what they need poor people for
To pay them small so they can live big.

Dexter44 meant that if we are all rich, nobody is rich because you can be rich if some people are not rich
I don't think we love the rich and hate the poor, we respect the rich that seems less dangerous in the day to day life because they are unlikely to rob you but to some extent we hate the rich and like the poor
