A hard Brexit with deep cuts to immigration would force Britons into longer working lives in order to maintain a sustainable ratio of workers and pensioners. In an article in The Guardian 'Hard Brexit means retiring later, Britons warned', Professor Sarah Harper discussed the dramatic ageing of Britain and the implications for work and retirement
“Since the middle of the 20th century, the UK, like many other advanced economies, has employed migrant labour to reduce the ratio between older dependants and workers, which has arisen as child-bearing rates have fallen and people have lived longer.”
However, if all migration into the UK was to be halted, then over the next five years, those coming up to retirement would have to work about one-and-a-half years longer just in order to maintain current output [of GDP]. Indeed, any significant reduction in labour immigration would wipe out the projected benefits to GDP of small delays in retirement, or require far longer working lives”.
