The middle classes will mortgage themselves to the hilt to pay for private education for their children because they naturally want the best for them, and/or have fallen for the marketing that says you don't love your kids if you send them to state school hell.
Ha ha ha ha. It's true.

They have obviously never experienced the hell that a private school can be. There's far more economic disparity there than public for one. And what if you're the only kid not going to Europe for this semester's excursion?
Ja'mie - Private School Girl is not far off the mark, I am told by ex private school girls themselves. (How funny was the final episode?)
Private school kids are led to believe they are at better schools than the general public, and are therefore better people. Every day. Year after year. Of course they are just normal... so... um, therefore the public school kids must be sub-normal. Again their own superiority is reenforced every day at home and school. This attitude continues on into later life.
The biggest **** heads I have ever met are ex private school. You perhaps have no idea. One introduced himself to me as "The Prince of the Gold Coast". I've met many others where two groups of friends collide that simply do not talk to "the other people" at the party. They would isolate themselves in other rooms for the entire evening, or in one extreme case the entire holiday, not mixing with the outsiders at all. I'm not joking or exaggerating.
Hello, yes, of course these are the extreme cases, hell I'm ex Sydney Grammar myself (they're all nerds btw, many from poor backgrounds/scholarships). But in general sending your child to a private school will affect their attitude to others and themselves, may create suicidal self esteem issues (a cousin ended up shooting himself after a school camping excursion), and may set you back $100,000s to create, ultimately, a useless, over-confident little prick.
Of the dozen or so people I still know that went to a private school none of them became anything of any great standing or "success" in society. Pretty average careers. Certainly nothing greater than my public school friends. Actually quite the opposite.

If I had it over again I'd send myself to a public school (I went to both), learn to stand on my own two feet, do it myself, experience and learn from some grit... everything the right wing actually stands for, ironically.
