I have experienced the disdain of those that think they are very successful. They treat others as stones to be walked on. I believe this indicates their character and that their success will be short lived.
It seems quite a mystery to me why others want to build their own egos at the expense of those around them. Is it something that we teach in our education system? Do we learn it from the teachers who belittle us as students? Perhaps.
Perhaps it is part of the character of each of us. It may be something in the gene pool. Whatever it is, the way of behaving is becoming more prevalent in corporations. Perhaps it is a good thing. Perhaps it is not.
