Maybe there is some feeling of jealousy in this country towards people on disability benefits. Now my head will probably get bitten off by the entitled for saying so. But although personally it doesn't affect me (and I haven't even heard of the keying blue badged cars, never mind keying them myself), but do you never wonder why that is?
People don't mind helping those in need, but when you have people who are struggling to make ends meet, who get no help themselves, if you have the attitude towards them that you are entitled and they are not, some of them might get a little frank with you (I am thinking of the woman at the school of one of the above posters).
Maybe its just that some people feel that the attitude of entitlement and "me, me, me, I want, I need, therefore I must get" has gone too far.
If in other countries, people manage with slightly less help, maybe that is why some people feel like this?
