Okay, taking Baltimore as an example, if you have a pod with five children, that's a total budget of $100k for the year. From some quick googling, Baltimore teachers have an average salary of just over $60k, but let's make it say $80k for a tutor to include the value of teacher benefits. That leaves a $20k cushion for food, field trips, classroom supplies, etc.

This basic structure is something that homeschoolers have been doing for decades as well, with $0 government assistance. In that case, you typically have a co-op arrangement where the parents share teaching duties for a small group of children. It's difficult but possible, and government funding would go a long way towards making those sorts of models accessible to more families. Right now it virtually requires a parent working part-time, which is something a lot of households struggle to afford.
