As to the non-answers of Laskern, the Ramban also gives as a reason what has happened in previous gilgulim. For example, if Reuven died owing money to Shimon and Shimon did not forgive him they will come back as Reuven as a rich man supporting Shimon the poor man. See Taanit 25a for a hint at this.
