That doesn’t change the fact that every month there are people putting money into that fund and people getting money out of that fund. The money you put in, is not the same money you get out of it. It’s still money that people working at that time, put into that fund. Nobody has their own personal savings account inside that fund. You only have a legal claim to a share of that fund once you retire, but that’s not the money from your paychecks and it’s not saved somewhere for you. A pension fund is not a collection of private pensions and it’s better that way. Because with inflation, your pension can increase, even though you didn’t "put in" that amount of money when you were still working. The government is able to increase pensions by shifting money from other parts of its balance sheet or by increasing debts or taxes to meet the pension demand. I’m sorry for Singapore if their state system works more like a private pension, because you don’t know how long you’ll live past retirement age, so you either take too much or too little out of that fund once you have retired and there is no adjustment for inflation. Yes, there are bad private pension systems. That doesn’t change the fact that you benefit more working in a worker-owned compay than in a solely-owned company.
