Why would we compare ourselves to an attorney, or a doctor anyway? If we were comparing ourselves to either of those, which we shouldn't, we should be compensated proportionally to the certainty of outcome. We should get paid the same as a doctor that almost never loses a patient, or an attorney that wins the vast majority of their cases.
Imagine a doctor @ 99.999999% success rate, or an attorney that could win above 90% of cases. Either one would be paid 7 figures, not 6.
