People are who snobs and arrogant never get far professionally. Those in very high positions are usually extremely likeable and sociable people. If you do not treat consumers as king or nurture your employees your business will fail no matter how much knowledge you have.
Then you get people who have no position but act like arrogant pricks in their own little niche, who cares really? And then you get those who have position and are arrogant, you can bet your bottom dollar they will stay in their same position for a longer time than someone with more charisma.
Most people who are arrogant are actually quite insecure people. They find the majority of their meaning in life by comparing their ability with those that they think are "lesser". They feel good walking through the public and thinking, Ha I am so special, these people never could achieve what I do, they are lesser than me!
I was like this was I was younger. Because no one I met could play the piano as good as me, even professional concert pianists looked bad to me! But this arrogance makes you bathe in the knowledge of "You don't know you don't know". You just don't realize that behaving in this manner highlights your own insecurity and sensititvity to self worth and limits your ability to learn and absorb wisdom. Abandoning these thoughts sets you free and then you can enjoy what you do without having to compare yourself with people. You will also learn a great deal more if you do so without the comparison of others" as a motivator. Your goals and enjoyment in life are achieved more respectfully (to yourself and others) if they come from your own reasons, not derived from what you see in others.
Arrogance limits your ability to learn, it is as if you are satisfied that your knowledge is saturated so far and high that no one can teach you anything new. Isn't life is about constantly learning something new? There is always something within us where "We don't know we don't know", arrogance puts a shroud over this issue. Every person you meet is an agent of wisdom and knowledge for you to learn from even if what they say goes against your ideologies.
For those who think they are being looked down upon, we have to be careful ourselves not to be self centered and arrogant! Why do we care so much if someone looks down upon us? Does that mean we are any lesser of a person? We should not have a superiority complex when we meet people who are more intelligent or able than ourselves. And if we think that they are being arrogant just ignore it and act as if you are wrong about detecting their arrogance.
