The ever increasing retirement age is another attempt at 2+2=5
It reduces the pension payout, at the cost of removing an employment opportunity for someone younger, while increasing unemployment benefit costs.
The elderly working longer can also lead to a risk of increasing health issues, with possible hospital care and an increase in sickness payouts, not to mention disruption to employers.
There is of course the other viewpoint . . . the longer you work, the less chance you have of actually reaching retirement age . . . probably financially rewarding for spouses, but I'm not keen myself
