Daft Sinkies still don't get it. CPF is hidden taxation on your disposable income, but they gaslight you into believing it's a legitimate 'retirement savings plan' like the USA's 401k.
And the few times you are allowed to 'spend' the CPF money, it's basically 'internal circulation'. For example, buying (leasing?) the 'heavily subsidized' HDB flats. It's like those tokens you find at game arcades, you can only use them at the various game machines within that game arcade, but you cannot spend them outside the game arcade or redeem them for cash.
Just wake up from your deep sleep already. It's getting embarassing.
