How ESSA's requirement on school level finance reporting may miss the point

I just read a new paper out from Bruce Baker and Mark Weber entitled "State School Finance Inequities and the Limits of Pursuing Teacher Equity through Departmental Regulation" and if you're a funding wonk type, I'd recommend it.
The upshot--and I'm oversimplying here--is that the requirement that ESSA has that school by school level finance reporting be done misses the real problem of funding inequity, which continues to be one of district by district. The district by district funding inequities are the issue we see driving the Foundation Budget Reform Commission in Massachusetts, the hangup over the state budget in Connecticut and in Illinois, insecurity as the new school year begins in Wisconsin...and I could continue. As Baker and Weber point out in the paper, equity in funding lies with the states, not the fed, and until district by district inequities are dealt with, we're missing the crux of the problem.
