IIRC, Snape hated Potter because James bullied him and married the girl Snape crushed on, and Snape white-knighted for her to the end of his life. Nothing to do with hard work vs. innate talent (and the books depict Snape as being a prodigy at potions, given how while in school, he made corrections to his own textbook to the point that the book was later effectively the equivalent of a cheat-sheet while Potter never really shone in any classes through inborn talent or hard work.
So not really a "hard worker hates natural talent" type deal here.
