I do have difficulty with this “significant” definition. For instance, if someone was already working in an effective career, then they would not qualify. But I guess as long as you could argue they were the best person for the job, they would have some counterfactual impact. Also, effective careers tend to be paid below-market wage, so the worker should get credit for that. These things together could easily equal 10% of the wage, which would then qualify (because we want to give the donor much of the credit for the salary itself).
