The parent contributor has conveniently left out the fact that the 37% of CPF contributions is split 20-17 in terms of employee-employer contributions[1], and has a ceiling of S$8000[2], so if one earns more than that, every additional dollar goes entirely to them, which is also taxed at globally low income tax rates[3]. One can put all one's post-tax money into any stocks/bonds/funds, and there is also no capital gains tax[4].
