If there's one thing I've learned in life, it's that we don't have a clue about what other people think. One of the biggest causes of problems in relationships, among people, and in anything that involves people's getting along with, or liking, other people is one person's believing he knows what someone else is thinking.
People so often believe they understand where the actions of words of others come from, what the other person's motives are, etc., and so often it's all just a matter of assuming. Worse, when we imagine what others are thinking we have only our own frame-of-reference to do that from. As a result, people often assume others "operate from the same place" as they do, when so often others are operating/coming from a very different place.
So, my reply here is that I know I don't think I'm better than anyone else when it comes to being "generally equal" or "of equal value in this world" or being worthy of respect. Neither do I think I'm not-as-worthy as anyone else.
Over and above who is equal "as a person", we all have different skills or traits. When it comes to individual skills or traits, some people would "score higher" than others, and that's fine. Someone else would excel in a different set of skills or traits. And, when it comes down to it; even if one person would "rate higher" on a huge number and variety of skills/traits, while another would "rate lower" on the same mix of the; all that stuff is superficial when it comes to the measure of a person (which brings us back to the thing that when it comes to "as a personal overall", nobody is better than anybody else).
I give people the benefit of the doubt when it comes to my own assuming that a whole lot of people think very much like I do when it comes to the "thinking one is better" matter. I don't think most people "think they're better". The biggest cause of trouble, however, is that so many people assume others do. :/
