It is not about being rich or super rich. It is about climbing the hierarchy being an exploitative act in itself. If you dream of creating your own business you will - you have to, basically by default - do this by exploiting other people on the way up. Your success and you becoming “mildly rich” is always built on the backs of others.
Edit: just to be clear, I am fully aware that in the greater scheme of things, a person earning 30k or even 300k is not the enemy of someone earning 25k. Obviously we need to get rid of pervertedly excessive wealth. Having 300k-30k-25k hating on each other distracts from the bigger problem.
But at the end of the day, and I say this with as little moral judgement as possible, as soon as one person controls another one’s salary and undercuts it for their own profit, we are in a system in which success is achieved via exploitation. And this is the case in 99.9% of work environments.
