Like all this "why should those with private pensions get state pension?" nonsense.
How long do you think a state pension that's not for the incredibly old or sick (as it was when introduced) will persist if the people who find it get nothing?
Many people say "I paid for 40 years" but don't add up what they paid. £10,000 of contribution buys you ~£500 per year of income. If you're paying a couple of hundred pounds a month of NI to fund NHS and pensions, you haven't paid anything like what is required to fund your state pension. Others are subsidising it for you, hugely.
And many don't mind that. But to then suggesting confiscating theirs, which is worth a fraction of what they have paid in because they are subsidising yours... how long do you think they would do that for before there is the political pressure to scrap it entirely?
Same issue if you start taxing higher rate taxpayers who pay for just about all services for everyone else on their pension contributions. At the moment it is fair: everyone pays in tax free and is taxed on withdrawal. You start to tax them when they pay in and pay out? Really?
This is how divisions in society are created. Either you can have a system where everyone pays in a fair amount per their salary and everyone gets universal benefits so everyone buys in.
Or you can have a system of everyone for themselves.
Purportedly we have the former but it has been pushed to its limit deliverately for over a decade now with a small proportion of people funding everyone else and getting less and less back.
I believe this is on purpose, so that public services and benefits lost support from those funding them and can be scrapped. I do not agree with this. And unfortunately those proposing to hammer the people currently paying for them is playing into the hands of those trying to engineer this.
To fix it, in our situation now, you need everyone working/ with unearned income through shareholdings etc paying higher tax and benefits/ services being staunchly defended/ reinstated as universal. If they are not then they will vanish entirely within a decade or two, having been repeatedly downgraded in the meantime.
People need to wake up to the game being played. Spite directed at those with even slightly more when they are not causing the problems.
If you want to move towards a social democratic system them means testing state benefits or child support and taxing only the group in the middle who have been paying the bulk of everything for years is the exact opposite of what you need to do.
