Equity is about justice. It’s an ethical issue. If you cannot understand justice, you cannot understand equity. Very simply, when a majority group uses its power and position to enforce its cultural norms and policies on the rest of society, they benefit or at least are not harmed, and further their own group. And this becomes so embedded in the society that the injustice becomes “invisible” it is just accepted as fair. Something as simple as where a highway is built heavily skews to minority neighborhoods being negatively affected.
Understand this. Then you will understand equity is fundamentally about justice and if we don’t seek to establish justice then we have failed.
