I think the solution is complex and will never please everyone.
One big issue with the demographics is we measure number of children per woman and say the fertility rate is X, but women are having children later in life, on average, which means a fertility rate of 1.8 (or whatever) masks the true demographic change that has slowly taken place since the 1960s. We not only have fewer children per woman but the timing means we have fewer generations.
Take my family for example. Me and DH are both the oldest of two. My MIL born in 1946 had DH at 34. My DGM born in 1945 had DF at 16 who had me at 22. That’s a whole extra generation less on DH’s family tree than on mine since the mid-1940s. That was before the average age of FTM went up but illustrates the point. Without those extra generations we are losing working age people even faster than projected.
PILs have lived longer than my DPs as PILs are now approaching their 80s and my DPs died in their 50s and all but one DGP did. My family worked in factories. The factories and mines built this country and generations of workers were slowly worked to death to build national wealth and when the factories and mines were taken away, there was nothing for a huge cohort of working age people to do. We’re about 2 generations down from the closure of the mines and most factories and we still have nothing for people with this social conditioning and skillset (which is not every descendant of a miner/factory worker obviously, but there’s a significant number of them/us who are long term unemployed and we’re pretending this group of long term unemployed came from nowhere). Leading to MH problems as they are shoved into jobs they aren’t equipped for socially. Leading to more costs in NHS and benefits. And less contribution than if we’d just left income support alone.
People on this thread have said you need a pot of 3million to have a decent retirement but the vast majority of people will not earn that in their lifetimes let alone have it spare to throw into a pension. 😂🤦♀️
Everyone deserves a pension. We can’t leave people destitute. But what is the answer? How do we balance the books when everyone wants free money or for the government to subsidise everything (they don’t just want it, they believe they are entitled to it) and yet no one wants to pay for it or to do what needs to be done to improve the country’s economic output? Of course people vote for more free money, letting people stand for election on that platform has given away the keys to the banana plantation!
