In hindsight those stable pensions were actually extremely immoral in a way. They allowed for a demographic moment where a large portion of workers consumed everything they produced with too little saving while supporting a much smaller number of retired and simultaneously telling themselves the next generation would pay for their retirement needs.
Well as 1 millennial all I can say is fuck that. I didn't sign up to support your prolifigacy in your youth and have no intention of doing so (to the best of my ability).
If you want a stable pension alongside an often decades long retirement, then start saving when you're young or have a lot of children to support you.
