Inequality has nothing to do with feeling superior or inferior to others (though, our culture absolutely does encourage those beliefs).
In a world with limited resources, huge levels of inequality necessarily means that a small group of people are consuming vastly more of the available resources than everyone else. It also tends to concentrate political power in the same small group. Many people would say there is something inherently unfair about this.
I think these things aren't as separate from your concerns as you make them out to be.
