Well I see what you mean. However I was raised to believe that one's freedom stopped when it hurts others. And I truly believe that allowing some to by-pass the education or health system via their purse- is not without a very strong effect on others.
To go back to education- most Comprehensive schools, as has been said already, are not comprehensive at all due to the creaming effect of private schools and other academies, religious schools, etc. Once parents can by-pass the system, the great majority just forget about the rest- as their child/ren is/are ok- and the knock on effect if multiple. Funding, but also parental support, facilities, etc. Not only do private schools get much more money (plus charity non tax status- which I could never ever understand!)- but also parents are influencial, politically and financially, and many have much time for fundraising for even better facilities.
I know many of you have told me before they are not interested in how things are done elsewhere- but here goes. Here, apart from major cities with lots of expats like Geneva, Zurich and perhaps Zug- there are no private schools. All the children go to the same school- and therefore, rich and/or parents with influence- are together- Not only to they learn from each other, immigrants, poorer families, those with difficult circumstances, etc- but the better off parents (financially or otherwise) work hard to ensure their kids have the best education and facilities possible- and that means that all the kids get the best possible- not just theirs. Can you see that? That also means that later on, the rich, the middle, the poorer, are still friends- and there is not such a big social division, the distrust of 'them and us' - which has a real effect on society.
The name of this highly Communistic country-
Switzerland !!! Same in many Northern Europe, where preventing social divisions is very important. And neither of them are Communist either.
A divided school system = a divided society- right from the start. Again, for me, freedom stops where it has a serious effect on others. I also truly believe that our daughters have been so successful BECAUSE they learnt from an early age to cope with different people- as they are now able to communicate at all levels, from one extreme to another- something which does not come so easily to those who were 'segregated' from a young age- so I'd always refute the attacks (which we've had in the past, as most of our friends and family sent their kids to private schools)- that we 'sacrificed' our children to our principles.
