@lyrala You don't get it do you. Some older people work part-time to top up their finances. But without a state pension a lot of people will have to work full-time. It is a very different prospect working a few mornings a week at 70, to working full-time. People who own their own homes don't need as much to live on, if you are renting you need to earn as much as you did when you were 40. Yes you will no longer have kids to support, but for lower paid workers you will no longer have the benefits that come with kids. So you need to still be working full-time.
And for those who own their own homes but are in lower paid work, they still need to work a lot of hours to achieve the minimum income guarantee that older people currently have. Sure they could work 3 days a week and take home £900 a month and scrimp and save to survive. But a pretty shit life. Most will still try and work full-time so they actually have some money to enjoy life a bit.
There is no point people in lower paid work saving anything into a private pension if this kind of thing happens. And those in state private pensions that mean you cannot take them until state pension age are totally screwed.
I don't know what kind of jobs people in these think tanks do. But I work in an office job, not a manual one. It is demanding though with lots of deadlines and outcomes to meet.
