Let's fix the injustices we are aware of today. (E.g., the effects of racist housing policies that depressed wealth for generations of Black Americans.) As soon as we're no longer able to point to obviously and deeply unequal opportunities, then we can stay figuring out how to know when we're done.

To build a coalition, you have to get the coalition to agree on a goal and a path or at least the right first step(s). Maybe some of them believe that nationalizing public education is a shorter path; others believe that early childhood nutrition is their preferred way to make fastest progress; still others believe that race must be explicitly excluded because it’s an imperfect proxy; others want race to be front and center in the discussion because they think it’s more than just a proxy. If you think X is more important than Y, you may not want to sign up for “Y first; then after we do Y then maybe we’ll consider X.”

This goes triple when X and Y both require some common resource. If it was possible to fix all of the apparent inequalities at once, it’s fair to ask why hasn’t it already been done? I think the answer is usually that you don’t have enough “oomph” to do everything at once, especially when there’s a risk and low appetite for over-correcting to create new inequalities from the program designed to eliminate them.

Coalition building is hard, even among people who 70+% agree on how things ought to be.

This is standard triage procedure, we don't halt all treatment until we've sorted through every possible procedure the hospital could provide. Instead, we look for areas that need our attention now and try to get them at the front of the queue.

Triage staff aren't seeking the best, most optimal first patient. They are trying to identify problems that need our attention.

Doing nothing is not always a sensible default.

That's the sense in which doing nothing is a sensible default for a career politician who wishes to extend their career.
