No way. As I said - people give to society in all sorts of ways and the vulnerable must be provided for by a civilised society - as well as those directly who give so much care but have a great reward in a child's developments - no matter how slight or big.
I sometimes feel bad that the NHS spends far more on my disability than I put into it (remembering a lot of my taxes go towards horrible wars and roads I don't drive on etc.) Although the whole Postcode lottery thing upsets me - those of us that need help should receive it.
Best wishes to you x
