OP, how much do you think it costs to accrue a private pension of £21k which would take pensioners to minimum wage? Do you think occupational pensions are free? Regardless of occupational pensions, people still pay NI. If they are not going to get a state pension are you suggesting they get their contributions back so they can add them to their private pensions? What would fund your childcare then, in your quaint ‘household budget’ analysis?
At what level of income would you withdraw the state pension? Are you saying that all pensioners should have to live on minimum wage levels, for instance? Or a mean average? Median? Mode? Whichever way you cut it, it would require a massive increase in the pension, as people who can’t afford to save enough to have even a minimal retirement income would withdraw from pension schemes and rely entirely on the state. So there goes your free childcare, as the mythical purse would be empty.
Pointless asking, I’m sure, but how do you justify keeping people who have paid tax all their lives on poverty levels of income with savings means tested out of existence?
Do you have savings? A mortgage? If so, do you plan to hand them over in 30 years or so, as you won’t ‘need’ the cushion they provide?
