How would feel if other people accomplished 1/10th what you did? What if they got paid 80% of what you got paid too?
What if teaching them took so much of your time that it was faster to do it yourself than hand-hold them through the process?
What if, despite producing more than the rest of the team combined, management saw you as a problem, and wasn't interested in your perspective now that you had a reputation?
Have you asked "the jerk" to be more polite about his feedback? Have you explained why it's important? Have you listened to his perspective?
