getting - I find this whole thread fascinating, and a lot of it is not at all black and white and I think almost all of us have a particular take on it that is, for the most part, understandable.
I guess the whole thing is "where (not just how) do you draw the line?" Inevitably, there will always be people who put their bit in and don't get much out. I'm one of them. I won't ever claim child benefit. There are probably other credits or benefits that I may never claim. Such is life. Then there are others who will claim continually even though they don't need it. Again, such is life. It's about making it as FAIR as we can.
We all benefit to some extent from our taxes paying for roads, fire service, NHS, police, rubbish collections etc etc. Should hrt payers who opt to send their kids to private school get a rebate because they aren't benefiting from state schools? Maybe. Should I get a rebate because I won't ever claim child benefit? Maybe. I think dig is right, that if you don't claim things in Germany you DO get a rebate.
It seems to me that there are some things that must always be sacrosanct as part of our society. I think providing state education until the age of 18 is a given. Universities, I am not convinced on. I think that if someone opts to study, say nursing or medicine, there is an argument that the state should fund that in return for a commitment to spend X years in the NHS to 'pay it back'.
I think the problem for some of us is where there seems to be a disparity in attitudes. We make choices. If someone who pays hrt can afford to send their child to private schools, their choice, if they can afford it. Sadly, some hrt payers have an unfortunate attitude and sense of entitlement which puts people's backs up. I'm not sure you can really compared the two - one is a definite CASH benefit, the other has no 'perceived' value (not sure that's right word, but hopefully you'll know what I'm getting at).
As I said before, I think it might be better to scrap child benefit completely and introduce something else that is more tangible - free creche/nursery facilities for all children between 1 and 4 (to enable parents to get back to work if they so wish). I think there is an argument to say that if you are JOINTLY earning £70K+ you should not receive child benefit, certainly not after a second child.
