As I see it, here's the problem, ignoring the issue of school safety for the moment: If we adopt distance education as a major delivery system, we will put disadvantaged students at an even greater disadvantage, as you point out.

If the coronavirus were vanquished tomorrow and we return to face to face teaching, we are still putting disadvantaged students into a system that insistently preserves educational inequities. In a way, the inequities made explicit by the technological divide are not as serious as the invisible ones (invisible to everyone except the disadvantaged students themselves), because it's clear how to fix them.

We need to think two steps ahead: during this upheaval, we need to address and start rectifying the two-tier system of public education vs. elite private education. Otherwise, when we return to some semblance of normal, the systemic discrimination in the system will also seem normal.
