All things being equal, I'm sure a random sample of children from the top SES quintile will have better educational outcomes then the bottom quintile (as measured by test scores, graduation rate, lifetime earnings, pick your metric). However my anecdotal experience based on my own background and other unschoolers I know is that unschooling specifically is not biased toward the wealthy. Rather it seems to correlate with parents who for whatever reason are willing to go far outside societal norms and the comforting embrace of social proof in the interest of doing what's best for their child. This isn't a value judgement one way or another; that statement could apply as much to an anti-vaxxer as an unschooler. The point I'm trying to make is that if a family enrolls their children in private school, hires tutors, arranges legacy admissions to $ivy_league_school, etc, no one will question the advantages they are conferring on their children. If instead they keep one parent at home and unschool their children, they will be doing so against a very strong current of social pressure, likely including their own extended family, and depending on where they live they may be acting against the will of the state itself. If anything, homeschooling in general is a way for families who lack the wealth to buy into elite education to try to provide their children with better educational opportunities than those afforded them in the local public school. It requires considerable sacrifice, particularly if it means giving up a second income and moving to a cheap place in the country to make the numbers work. Whether or not it's actually better for the children in question is ultimately up to the parents. I count my hybrid schooling/homeschooling/unschooling experience as a privilege in the sense that it's made me better than I would be otherwise. But it has nothing to do with wealth or income. I could arrange to be born 1000 times to 1000 wealthy families and not have the same advantage as I did with my poor family.
