Everyone born after say, 2006, should pay less NICs and be mandatorily enrolled in an Australian style pension where you must pay 9.5% of your pre-tax salary into a pension fund. Even part-time, term-time, ad hoc workers.
I worry often about whether the state pension will exist when we are older. Will it be means tested? Can it go on with an ageing population?
A solution along the lines of the above would let the younger generation know where they stood.
