4 = 4
If one team wins the Super Bowl, and one team loses the Super Bowl, then those teams are not equal; that is not equality. But if the game was contested fairly, with no cheating or corruption, then the outcome is equitable, even though it’s not equal.
In the U.S. what we generally strive for is equality as an input and equity as an output. If you hire two people, each should have an equal chance of contributing to the business, i.e. neither should be inhibited by irrelevant factors. But it’s expected and ok if one contributes more and advances farther. If it’s based on a fair measurement of their performance, that unequal outcome will still be equitable.
That’s why you’ll often see folks talk about “equality of opportunity.” Not equality in general; equality as an input.
