It takes some doing to be more ignorant and selfish than Essex, but I think you've managed it.
If I get to the end of my life without the need for medical support and recieve less out of the NHS than I've put in, then I'll consider myself very lucky and a winner.
Because my contribution could have been used to treat a child with cancer, or to have paid for an AIDS test for a rape victim, paid for the defib that was needed to save a fellow Oxford fan at the Wycombe game a couple of years ago, or to have help provide hospice care for someone in their last days. Or any one of the millions of other interventions the NHS covers every year.
It's not perfect, but the NHS provides the same care to everyone based on need not your bank balance, and that makes us all winners.
