What truly amazes me is that you don't realise how ludicrous that idea is.
Let me lay the facts of life to some of you folks because it seems that none of you have interacted with the globally competitive real world.
Your entire GDP is also your entire national income. That is £2.4T
Your tax revenue now sits at about £1T (highest burden in 40 years)
There is no magic money tree now beyond that £2.4T of national income as you cannot borrow more. The market has empharically said no.
If you want "higher pensions" you need to grow that £2.4T
Without doing so (what you are doing now) you are robbing Peter (taking from younger generation and future) to pay Paul (pensioners).
This makes the UK POORER because pensioners consume, they are not productive like the working folks, so that £2.4T simply doesn't grow.
Thats precisely one of the drivers of WHY you are seeing 0% real growth right now vs EU/US (which are growing based on pre-pandemic level of Q4 2019).
And the trend will get worse as rhe bulge of baby boomers retires and keeps asking for the same benefits (and yes, the state pension is a benefit the qualifying years formula does not change this fact).
Current long-term UK GDP growth sits at 0.8%
In order for the UK to be on a sustainable demographic footing it needs to be 2-2.5%.
What the pensioners don't "see" is that eventually they will kill their golden goose (the Greeks found this out the hard way).
Wait till State Pensions start getting to 15% of all public spending (£150bn of £1T it is £120bn now), and you will see how much worse public services (NHS and Education) will get.
At the end of the day, if national income does not grow (same pie), you simply make some people poorer and others wealthier to the long-term detriment of the country as a whole.
