We all know that homeschooling is much more effective than schools, especially public schools (I feel sorry for kids who have to attend nonselective public school in Western Sydney, imaging keep your child locked up with lebs and children of losers for 8 hours a day, 5 days a week...), so why aren't it more popular?
Well, not only will your parents lose some income which they want to save up for their retirement rather than spending on you anyway, they simply find their job more interesting than teaching you. And if your parents don't speak English or are so uneducated that they think the public school system would do a better job, in that case, I feel even more sorry for you.
Sure, you might argue that "I went to a non selective public in Western Sydney and got ATAR of 95", yeah but you're the rare one, doesn't change the fact that your parents didn't care about your education and left your education at your own disposal. They think that they have fulfilled their parental responsibility simply by giving that responsibility to the state, (or if your Asian, the state + some private tutoring), instead of teaching you like those real parents that actually gives shit about their parental investment in their child.
So if you go to a shitty school full time, your parents simply don't love you.
