But we don't do that with working age benefits. My taxes go towards working age benefits of others. I've not claimed job seekers benefits or any type of income support since the few weeks I had to after graduating in 1995. However if something happened to me and I became unable to work or got made redundant, I am very glad of a system which enables me to claim it. There is no way to foresee what private pension pot someone will have accumulated by the age of 50 when they're just starting out in their early 20s. We will always need a backup social security pot for people whose pension plans go awry through no fault of their own.
And what do you do about feckless or incompetent people who burn through their private pension pot and end up with nothing left after a number of years? Throw them out on the streets? Send them to the workhouses? You can't tell them "well, it was your fault, you deliberately chose not to save into the state pension scheme so now there's not enough in the public pot to go round everyone, so you get nothing." How do you prevent that situation?
We're already on dodgy ground giving people choice over how to use their private pension pots when they just aren't financially savvy enough. Is there going to be someone there to say "no, you're drawing too high a percent each year, you're not going to have anything left by the time you're 80." Annuities are one thing, but drawdown as a choice is way too risky in a system in which a person's ONLY source of income is that pension pot, and there is no state backup for them.
