> Find me one serious person who has ever argued for equality of outcomes.

Without commenting on or evaluating the merits or demerits of the argument, here is a representative example:

“Equality means each individual or group of people is given the same resources or opportunities. Equity recognizes that each person has different circumstances and allocates the exact resources and opportunities needed to reach an equal outcome.”

This was a widely held stance in certain circles. Additional examples in different domains/disciplines are not difficult to find.
