The idea is that when people are older, their dependents are likely to have grown up and earned their own income also, so life insurance coverage won't be necessary.
Life insurance (insurance that pays survivors when the policyholder dies) helps protect dependents against the loss of the policyholder’s income from work when household wealth is insufficient to self-insure. (And conceivably against the loss of some other income tied to that person’s single life, such as life annuity income, although that’s much less common. Note that “income from work” could include non-market income in the form of home caregiving for dependents.) When the person has stopped working, then dies, death can be a
good thing, financially speaking. It‘s certainly not an insurance necessity to pay for a policy that pays some benefit when the financial aspect of the event is beneficial (or at least neutral), not calamitous.
The downside of having whole life or cash value is that the upfront premiums are also much higher.
That also means your dependents get less protection per premium dollar, so it’s common for whole life insurance buyers to underinsure — for example, to skip Disability Income Insurance because their whole life insurance premiums are so high they can’t afford to insure against the even more catastrophic risks associated with disability.
A 30 year old (31 age next birthday) male nonsmoker can buy S$400,000 of term life insurance (with TPD) coverage, term to age 65, for S$256 per year (Etiqa). To buy when expecting a child, for example. It’s S$788 per year if you want to attach a Critical Illness accelerator rider. Premiums are guaranteed level, and you can stop paying for the policy any time you’re ready to self-insure. That’s a lot of protection for not much money. This sort of premium frees you to protect against other calamitous risks (DII!) and to save more in long-term investments to build wealth — wealth that’s also available for any genuine emergency, not just the claimable ones.
