At the moment, 66% of Somerville district public school students are eligible for subsidized school lunches, meaning that their family income is below 1.85 times the "official" poverty level (that comes out to ~$31K for a family of four). I'm sure all of their parents would be thrilled to take time off work to support a DIY home schooling program without any government involvement at all. =/
