Where will we be in 20 years?
I hope, OP, that you ill be confidently heading towards your retirement secure in the knowledge that assertive public opinion in support of the state pension has ensured that there will still be one for you.
I have just reached state retirement age, having worked my whole life in a low paid charity sector (with a proven impact of having saved the state millions of pounds in other services costs), and for the vast majority of my working life my employers made no pension contribution - and when it became illegal not to it was at the lowest legal amount. I did start a SIPP when 'opting out' was the thing, so luckily have a tiny bit more than the £11.5K of the new pension amount to live on.
I am so frugal with heating atm but I know that in 10 years time I will need to keep my house warmer than I do now, god knows how those bills are affordable on £11.5k + £200 fuel allowance.
If the pension isn't enough to live on then people beg or die...or enter the administratively costly Pension Credit system.
It isn't pensions that are breaking this country economically and lashing out at the most vulnerable just takes our eye of the bigger issues.
It is incredibly hard for young families on average wages now - state help comes in the form of Child Benefit, free nursery hours, tax credits, etc. UC is also increasing. More free nursery hours. NI has gone down a bit (whereas tax remains the same so pensioners with private or other non state pensions have not been given a tax break).
Be careful what you wish for. Older age comes sooner than you think.
