Everyone in the class should get an A, no matter what. No one should enjoy a better education than anyone else, no matter what. We want some combination of material incentives combined with guarantees of economic rights. Taxation should be somewhat progressive, but not punish good behavior. This means that educational funding and access is particularly important.
Equality of opportunity is probably a better principle than equality of outcome.
Grading in this class should heavily reward effort, as well as performance. I don't know the answer to this because the Statistical Abstract of the U.S. doesn' t include this information. Because the government doesn't regularly collect data on wealth distribution. In 1997, the average CEO earned about 329 times as much as the average factory worker. Back in 1960, they earned only about 40 times as much.
