I agree with SJS.
I have two frum families homeschooling on my block. To say “most families can’t do it” IMHO is a cop out.
Additionally, its easy to say “it can’t be done”. In Europe it was done. If you are serious about your’s & your children’s yiddishkeit it can be done.
If you “don’t want to” and are willing to live off Tzedaka, then it can’t be done. That has become a more than acceptable outcome in the Jewish world.
So my answer to the OP is simply “no”. Live off others’ Tzedaka like everyone else.
