No, one can't jump the queue in A&E and thank goodness for that but if you are suffering pain and need an operation you will have to join the queue and it can take months if not years of waiting. Most of the private health insurance companies offer you the additional choice of being able to claim back refunds on the cost of private consultants, I can claim 50% back in doctors and consultants fees at the renewal date of my policy every year.
I would agree with Brendan's analysis that young people don't really need the additional cost of health insurance because on average they are very healthy but as one gets older it really is a great source of comfort to have it, we have all seen the awful stories of people dying while waiting to see consultants for bowel and breast cancers. I strongly feel Universal Health Insurance for all is the way to go then everyone is treated with equity and dignity and it would also be a much cheaper option for all of us.
