Homeschooling is growing and will continue to grow because it is a cheaper alternative to private school (for people whose incomes aren't so high that the loss of one income eclipses the savings of not paying for private school, e.g. most people). The growth of homeschooling is probably highly correlated with the disconnect and distrust people have with public school. Public school already has an advantage, it's literally free. So it has to have noticeable problems people feel like they can resolve at home, for people to want to leave it behind
That depends. Often it means one parent stays home to educate and watch the kids, otherwise, someone else has to, and that usually costs money. If a wife otherwise would bring home a decent salary, then it isn't cheaper.
