  Which immigration will not solveâ¦â¦  Sorry if my post was confusing, but it didn't mean that immigration would solve the problem. It won't and will only open up a whole other can of worms.    My point was that obligatory public pension system itself is the problem. The money is not used to invest and actually look after the pensioners, but is treated as an entitlement piggy bank for bureaucrats and is no better than a game of musical chairs. New people have to come into the system to pay for the retired folks, and with a system based on logic like that then a shrinking population will certainly cause it to fail. Nobody ever seems to talk about where the original funds went to or why they weren't invested properly to actually be able cover the pensions of those that payed into them. It's another tax at best or pure thievery at worst.    This year, the Japanese government conveniently lost many millions of pension payment records and is putting most of the burden of proof on the payees. The incompetence involved is epic and the more likely explanation is that this is the Japanese governments way of writing off a debt to it's people that it knows it can't in reality pay in full.
