Life insurance works by sharing risk among policyholders and using statistics and probabilities to ensure payment of claims even when a small premium is paid. The government establishes safeguards like solvency requirements, reserves, regular financial checks, and cease and desist orders to ensure life insurance companies remain trustworthy and policyholders' interests are protected. Worst case, a security fund or forcing the liquidation of assets protects people if an insurer becomes insolvent.
