What's annoying about these debates is that the people who'd e.g. like to see pension cuts are either young and will change their mind later, or they are so rich that none of this matters to them anyway and the latter shouldn't even have a voice in this debate.
The issue is the "triple lock" (state pension rises by either rate of inflation, average earnings increases, or 2.5%).
While laudable in intent, recently this has led to situations where pensioners are getting bumper increases linked to high inflation, while the younger working age people are getting stagnant wages while inflation shoots up.
This is is why pensioners are on average getting wealthier than the working population. Let that settle in for a moment: pensioners are getting more wealthy than the working population that is financing the pensioner's increase in wealth.
This is universally accepted as unsustainable and deeply unfair on an intergenerational basis as the pensioners - who generally tend to own their own homes and also get various benefits like free transport and extra money for heating costs etc as well as benefiting from more generous policies/working conditions of the past like free university education and final-salary private pensions or purchasing government-built social housing at steeply-discounted rates - continue to get more and more well-off while the people financing their retirement are struggling with soaring costs, zero-hour contracts, stagnant wages and all the rest. Yet pensioners complain that they paid their taxes so they deserve to cripple the current workers who also pay their taxes.
Trouble is that it is a political landmine since pensioners are a big part of the vote so no one has the balls to abolish (or at least reform) the triple lock.
The way it usually works is taxation from the current working generation pays for the current retirees. You are not paying into your own account for later (that is a private pension)
FWIW in the UK there are more children in poverty (so their parents too) than retirees who are in poverty. Kids don't vote though...
