>you bet your welfare on a hope that in 40 years time, there will still be enough cash flowing through the system to support you.

Yeah. Finland has a system similar to Sweden in many ways, in general it has worked great. Though during last decade or so without much economic growth and upside down demographic pyramid, some young people who follow the news have started to look at it with some suspicion. Current pension payments from our salary goes to current pensioners, but our retirement age is moving up and estimated future pension payments going down. Then in last year or two the birthrate dropped dramatically, and I updated from "concerned" to "heavily worried".
