The reason why education is a requirement is simply business thinking of the employer. Proper educated people are brainwashed for team playing. They are integrated into the system and don't tend to break rules. Rules are what will be set on them in order to implement them into a trading job and keep them there under strict monitoring. The industry is not looking for the best but for those who are easy to drive. The employer knows a good talented trader who is creative and equipped with the necessary discipline for success will not stay.
