This House, as a young person in their 20s, would choose to pursue FIRE over voluntary social insurance.

"(1) Financial Independence, Retire Early (FIRE) is a movement of people devoted to a program of extreme savings (usually 50-70% annual income) and investment (on average 10% annually minimum) that aims to allow them to retire far earlier than traditional budgets and retirement plans would permit. [Mathematical background] FIRE followers comply with the 4% rule, and this simple formula for calculating your FIRE number: Annual Expenses x 25 = FIRE number. It means when you reach the FIRE number, you no longer need to worry about working, because you just need to withdraw 4% from your portfolio annually to cover your expenses. (2) Voluntary social insurance in Vietnam is defined as a form of social insurance organized by the State in which a participant may select a premium rate and a method of premium payment suitable to his/her income and the State supports his/her payment of social insurance premiums for him/her to enjoy retirement and survivor allowance regimes. [Mathematical background] (+) The monthly payment is equal to 22% of the monthly income chosen by the participants of voluntary social insurance. (+) The minimum monthly income selected by participants of voluntary social insurance is equal to the poverty line of rural areas as prescribed by the Prime Minister and the highest is 20 times the base salary at the time of payment. (+) Monthly voluntary social insurance payment = 22% x monthly income chosen by the participants of voluntary social insurance."
