We do have an ageing population which is increasing the benefits bill due to state pension but an increasing number of people over 65 are working.
11% of over 65s working mainly part time doesn’t negate the other 89% though?
“The Office for Budget Responsibility (OBR) predicts that in 2023-24, average government spending will be £23,700 a year for 75-year olds and £32,400 for 85-year olds. This compares to £19,100 for 15-year olds and £7,900 for 45-year olds”
”As well as government spending being higher for the elderly, revenue raised by taxation on the elderly is lower than that for working-aged adults”
”For example, in 2018-19, the median tax payer aged 45 to 49 paid £3,140 in income tax, compared to the median 70 to 74-year-old taxpayer who paid £1,580. The elderly’s lower incomes also mean lower spending, and so revenues from VAT (which is added to the price of good and services) are also lower for the elderly”
And we already have more 65+yrs than under 15 yr olds so without immigration the pyramid is inverted which isn’t sustainable.
