Ah Alea, I said no-one here, eg where I live- sends their kid to private school- NOT Switzerland as a whole. There are some expat communities, like Geneva and Zurich, where expats have always chosen to send their kids (generally but not alo- I know some who wanted their children to integrate and learn the language, etc, but they are few) to private independent schools, that are often paid by the employer as part of a vast salary package. A few more low tax areas have now followed suit, like Zug, which is also full of expats. But generally, and certainly in rural areas- all the children go to the local school- whatever the parental background. Expats are putting more and more pressure ont he system here to change, and for parental choice (the concept does NOT exist- but of course it does in as much as you can pay for a house/flat in a better area- although generally 'areas' are much more mixed housing than the UK)- and this is being resisted very strongly- with my full backing (as a councillor on the education committee).
Some of the watch-makers here are multi-billionaires, but they choose to send their kids to the local school- all the professionals too- and they also spend time, effort and give financial support for extras, too- making the local schools better for ALL, not just their own kids. I like that. Having come back here after 39 years in the UK- I see the legacy of this every day- the doctor, the banker, the CEO of a large company, went to school with the guy at the cash till in Coop, or the one that clears the streets, or some of their workers - and it does have an effect on the way they behave towards each other and the way they respect each other. The all play at the same football or hockey club, or ski together at the ski-club- they know each other's families. I like that.
The education system here began much later, and was never saddled with the past history of 'public' ) (what a silly name!) - schools, and other private institutions, or religious schools, etc. A divided society begins at school- and the gap gets wider and wider- and is, in the end, NOT in the best interest of anyone, let alone one's own children.
Be it the NHS, or the school system. once parents/patients have voted out via their purse strings- they sadly no longer care about what happens to the rest. And it is a vicious circle. Wanted the best for your child should not be to the detriment of others- and does NOT have to. Supportive, influential parents can help schools be the best for all- and insist on it. Parents who pay upwards of 20.000 for their kids to get the best spend much time doing even more fund-raising and even more supporting, for those school and children- so what happens to the rest.
