If you really think it's unfair then you would have moved to Indiana to downward adjust your salary. Sounds like posturing to me.
The arbiter of the unfairness is the company policy. That's who we blame, not the employee who happens to benefit. They are no more to blame than the person who doesn't benefit. The causal relationship simply doesn't exist. I'm actually curious about the reasoning you applied to somehow pin the duty of responsibility to the employee that benefits?
