Intelligence over looked?

I think there are many intelligent people out there who are overlooked by employers hiring someone for a job,by teachers grading papers, and by many others around them. Who are these people, you may ask?
These are the people that many call average students,slow learners,and so on.
They are willing to learn,but often overlooked by people who think "I am above you" whether they say this or not.
Seriously, what is the so called EOE-Equal Opportunity Employer stuff all about?
Why is it that someone who takes more than a few days, weeks, or a month to figure out all the things to do in a job are given an unfair chance on how to learn more about how to properly achieve it, while others who are goofing off by listening to immoral tunes on their ipod during lunch are given more time to figure it out?
There are people who sleep at work all the time, lie about, and they get paid more than those who stay awake and take awhile to learn the job? Why? because their boss or the company does not really mean EOE, they just say this to try to avoid law suits based on intolerance, or rudeness towards others.
There are many authors,poets,inventors and more who when they first started out where told "you will never amount to anything", or "you are to dumb". Or call bad names, or had other insults hurled at them.
We'll guess what? The light bulb was invented by one of the so called "dumb people." So what do you think now? Huh? Thomas A. Edison was told by his own mother that he was stupid because he made less than straight A's,and his teacher said "I give up on Thomas Alfred Edison. He will never amount top anything because his grades are low,he is a distraction in class, and he is just plain to dumb." Who is laughing now?
He failed at the light bulb over 1,000 times and yet now we have a decent light bulb that accurately works. So who was right, the teacher,and his mom,or society?
He proved them all wrong! So, you see people with attention deficit disorder really are smart after all.
