From what I've been told by parents who have done it, it takes half the time. 4 hours a day is the usual, from what they say.

I wish I had 4 completely open and free hours a day to just devote to my principles. Sadly, since I've lost the government babysitter that covered most of my work shift, I now need to work double shifts to afford a professional one as both I and my wife worked full time to afford a decent house in a neighborhood that isn't crime riddled to begin with, which means the child needs supervision for the entire now open day.

Also, you've now removed the incredibly crucial socialization bit from schooling, which means you now need to devote way more than just 4 a day to making sure they get that proper education too in other manners. One of my best friends through high school was taken out to be homeschooled and I can promise you his daily life was way more than just 4 hours, and that was a mostly grown teenager who didn't need hard structure to keep focused.

Its easy to say when you are just watching other parents do it, but none of this is just that simple. Its a great idea in theory, but well beyond the physical and literal capabilities most parents have. Which makes your "you deserve it" crowing say more negative things about you than them.

it's far worse than that. schools intentionally slow kids down, can't have any particular kid excelling. 4 hour a day home school kids can easily cover 2x the material in half the time. there are tons of home school kids doing high school algebra by 4th grade nowadays.

shit, i went to public school, and if i finished in-class work early, the teacher's response was to do more busy work. a lot more. teachers intentionally stopped disclosing the homework until the very end of class so that kids who finished the in-class busy work would be intentionally stunted, and forced to waste time. i would do the entire homework that's supposed to take 60+ minutes in less than 5. it wasn't until 10th grade that i got to opt out of that shit with college classes.

it is incomprehensible to these people that others around them can be so much farther ahead.

I bet my cousin doesn't even average 2 hours a day and her kid is a teenager and has been homeschooled his whole life. I never quiz him on book stuff, but he's a very smart kid in the important ways like problem solving and common sense, well ahead of his age. He's also very independent in ways I don't see from other family that age. The school-goers seem to all be instruction followers now. I know if I ever have kids, homeschooling is not negotiable even if it means me quitting a good job to work at night in a sucky one and making myself get by. Not just for the anti-indoctrination, it just seems to make way more rounded people to me.
