Sure, I can agree with that. There does need to be some kind of incentive to do jobs that enough people don't naturally want to do. But the differences in rewards should be kept as small as possible and created only as a last resort. As I said, power concentration should only be allowed if absolutely necessary. If no one wants to become a doctor, then I'd consider it absolutely necessary to increase the incentives of doing so bit by bit until we have enough doctors while keeping in mind the risk that comes with the power differentials created. At some point an extra doctor might not be worth the extra risk of power concentration.
