There is no need to accumulate so much wealth if you plan to retire simply. There are many old retirees who retire by renting out their spare rooms in their hdb flat. They also get allowance from their dutiful children as well from their cash and CPF savings. For the richer folks, they sell their landed property and downgrade to a penthouse condo to retire. They use their cash to buy dividend stocks and annuity for their retirement. They don't depend on their children but if their children give them allowance, they keep the money in case their children need the money in the future. Those who retire in Malaysia rent out their hdb flat and retire in KL, JB or Penang. Some retire in Thailand like a rich man.
