The idea that we care about equity is important, but using race as a proxy means we need to care especially about the proxy and making sure the proxy is representative of the outcomes and how the inputs are effecting the outputs. And, if we're being honest, it's kind of an arbitrary proxy beyond the correlation.
We are already seeing huge problems here with men vs women using gender as a proxy for outcomes, where we've basically flip-flopped graduation rates, but since it's a lagging indicator, we've really gotten ourselves into a pickle where we are creating an equity problem while trying to solve an equity problem, because we're so focused on outputs throughout every stage of the life process that we're missing a massive shift in the inputs (like who we're graduating).
Equality is important. Equity is important. They are different things, that should have different attention. Equality uses identity directly. Equity uses identity as a proxy for outcomes. We need to be very careful when we focus too much on one over the other.
