Shelby Not everyone can afford to HE
Home ed is as expensive or cheap as you want it to be.
While many families may have one parent non-earning, it's not always the case; in my family, I work part-time in the evenings. Other families may have a parent working from home, another may have both working part time, another family may have both working full time, but opposite shifts, and yet another may have two parents working the standard 9-5, and they home ed in the evenings, and weekends. There is lots of flexibility. And yes, there are single parents who work who HE, single parents on benefits who HE, disabled people who HE etc. It is not limited to middle-class two-parent families at all (in fact, where I live, they are in the minority.)
The only expense for HE that is specifically covered by school, is exams (if you choose to sit them). If you are home educated, you will be classes as a private student and there will be costs associated with sitting that exam. However, there is [currently] funding for Pre-16s going to college at 14yo, to sit exams; not to mention that a child can be enrolled in a school in order to study and sit exams.
You do not need to use tutors or online courses like InterHigh; there are libraries, free online courses and other parents locally who swap skills (there are loads of ex-teachers who home educate!). Again, there are options.
I, otoh, look at schools with the constant outlaying of money for specific uniforms, shoes, trips, lunches, raising money for this and that, etc and school seems the more expensive option. It all depends on your perspective.
I'm not denying the fact there is also sacrifice, but arguably there is sacrifice whatever option you take: my parents sacrificed a helluva lot to put me and my sister through private school (no holidays, my dad worked full-time, my mum worked 3 jobs, etc).
As I said before, I'd be open-mouthed if a parent said that, assuming a free choice, they've purposely chosen an option that is not best for their child!
If you have looked at all options and you can't afford to HE, then that's not a free choice as you wouldn't be able to choose that option.
