Yeah.

It obviously is paid for somewhere along the line. It comes out of something we have called "National Insurance", or NI - essentially a tax.

If you earn £30,000 ($50,000) a year, you'll pay £220 ($360) a month to NI.

Your employer also contributes, paying directing to the government – about £250 a month ($410). You never see that money, it doesn't appear on your payslip, it's just something employers have to do. (In return, if you're sick, the employer gets money back from the government to help with your sick pay.)

NI helps to pay for your pension, but I suspect the majority of it goes to the NHS.

However, if I go to the hospital every single day and have every tooth replaced, every bone reinforced with steel and my wife has 10 babies, I still only pay £220 a month. And nobody checks that you do, soon as you're ready to leave the hospital, you just walk out. You don't even have to give your address. (But they like to take it, so they can update your patient records.)

Here's when it really works: say I'm 18 years old and I earn £4.77 (the minimum wage for under-22s) and I work 20 hours a week, because I'm on an apprenticeship, or I'm too ill to work anymore than that, my NI is £0.00, but I can still have as many babies or break as many limbs as I want.

The Prime Minister probably pays about £450 a month in NI. If you earn £1,000,000 a year, you pay £1,146 a month.
