Obvioulsy "taxpayer" has no concept of what it is going to cost the government to support the aging population in the next 50 years or so.
If you study the population pyramid of the UK (see below) you see we have a huge number of people in the 40 to 60 age group, and a SMALLER number of people in the 0 to 30 age group.
As the people in the 40 to 60 age group get older they will need to be supported (ie paid for) by those currently in the 0 to 30 age group, and there just are not enough of them earning money and paying taxes to do that.
If you think it is bad now it will get a lot worse in the next 10 or 20 or 30 years.
This is why the government are tryng to reduce the pensions of the public sector workers, this country just cant afford to fund pensions for a population that is living longer and expecting better care and support.
