Firstly remember that it is only the basic state pension which benefits from the “triple lock”. Additional amounts (which can be considerable and depend on extra contributions) do not and rise only with inflation. However, I digress.
The biggest problem is, of course, that the State pension scheme is not a pension scheme at all. It is simply an almost flat-rate welfare scheme paid to people over a certain age. Pension schemes generally have a relationship between contributions received and payments made. The State pension scheme has no real relationship like that at all. To take an example, a person earning £100,000 per year would make NI contributions of £5,333 (at today’s rates). Somebody earning £15,000 would pay just £833. Assuming both worked for the minimum of 35 years at these rates, both would receive identical pensions. Yet the higher earner would have paid around six times as much NI (and, incidentally though perhaps not so relevant, 37 times as much income tax).
The State pension scheme – as a proper pension scheme which relates contributions made to benefits drawn – is perfectly sustainable. What is unsustainable is to pay the same pension to somebody who has made little or no contribution as is paid to somebody earning (and paying in) many times more. (I won’t even begin to bring into the argument the issue of those who have made no contribution at all). Add to this the “Ponzi scheme” nature of State pensions and the system clearly is a huge drain on the exchequer (i.e. current taxpayers). However it is scarcely the fault of current pensioners that their contributions to the scheme have been frittered away by successive governments instead of being invested.
If the State is to run a pension scheme worthy of the name it should separate properly funded pensions (which should be paid according to contributions) from welfare payments for older people. That is what Ms Altmann should be lobbying for. Either this or get out of the pensions business altogether by reducing the amount workers have to pay in tax and NI, allowing them to make their own investments as appropriate. The State can then concentrate on welfare for those older people who have been unable or unwilling to make provision for themselves.
