If you want an enjoyable retirement you will need to fund it yourself - you are not entitled to decades (or even years) of leisurely retirement. State pension is just another form of safety net, and we cannot afford for everyone to take it. There will always be those that decline / die before the threshold (plenty cannot work into their 60s today), but we need as many people working or paying their own way as possible if we want to keep safety nets for those that cannot.
I think there is a mindset problem in the UK where too few feel any responsibility or urgency over retirement planning. Labour seem to be contemplating reducing tax incentives for retirement savings, which is the exact opposite of what we need. We want people to build big pension pots that will see them through retirement, pay care home fees, etc.
