I know that many rich people benefit from the poor staying poor. The harder it is to earn money or meet needs, the more the poor will work which makes it really easy for the rich ones. They have no other choice but to be productive.

If the poor stays poor or god forbid be even poorer, it will create a bigger class gap between the rich ones and the poor ones. The rich will be perceived a lot more rich if the rest of the world earned less than them. I have seen many cases where the rich actually benefits from inflation. Besides they do not experience inflation the same way the poor does. They can fight against inflation better than those who earn less.
