In US it is the 401K system, Canada has something similar. They also dont call it taxes but retirement pension schemes. Except you cant take it out for properties. Also, even when you take it out in retirement, you have to pay taxes. In Singapore, you claim relief and it is tax free when you withdraw at 55 onwards.
There is simply no comparison between 401k and CPF.
The CPF scheme works like this.... I'll take more than 30% of your salary but on paper it's still yours even though you can't use it. However, you can use it if you're willing to buy a $40,000 home for $400,000.
