While many people have paid their NI contributions and rightly feel entitled to use its services, the increased and varied demands placed upon the NHS today are making it more difficult to justify many types of treatment.
It was designed as a resource to treat the sick, but has developed over the years into a service that helps with medical conditions that are neither life threatening nor some kind of human right, like fertility treatment.

Even the originators were stunned and concerned about the amount of use the system experienced at its onset. One of the earlist concerns was the number of women seeking medical assistance to deal with conditions caused by years of child bearing with insufficient medical assistance. The number of surgeries to repair female prolapse shocked many politicians.
It would be lovely if the system could continue to satisfy all sections of the public, but sadly there will come a time when a government of one persuasion or another will have to bite the bullet and draw the line at what can and cannot be offered in a free at the point of service system.
I wouldn't suggest this is reform by stealth, but more a realistic attempt to cater for medical need rather than medical want.
