Reply To: Schar in proportion to potential

Derech Hashem makes it very clear that a person in olam haba is judged purely on ones own bechira “so no one has any claim against his fellow”. So a lowly doctor or a simple lawyer (why do we always have to make tailors and shoemakers the lowly guys?) will get as much schar as an accomplished and successful talmid chacham. Not every tzadik is a talmid chacham. Not every talmid chacham is a tazadik.

Why does one follow on from the other? I understand that one is judged on one own bechira, but why does that mean he gets the same sechar?
