It's all pretty much moot. Most of the work gets done, not by politicians, but by actuaries. And the Government's actuary has just concluded that NIC need to rise by 5% in order to maintain just the basic state provision. AFPS22, anyone? Means tested state pension, anyone?
Me, I think higher NIC is just a ploy to get people to retire. But wait. Let's combine Income Tax
and NIC..
