When individuals have no way to look after themselves, the government steps in, spending the public's tax money. This is the second principle of social welfare, the principle of care and protection. In accordance with market principles, however, beneficiaries are still required to bear a portion of the cost, which is called "costsharing."
而當個人無法照顧自己時，政府力量介入，用大眾所繳的稅支出，這是社會福利的第二個原則﹘﹘照護原則；但仍要求享受福利的個人分擔部分費用，以符合市場原則，是所謂的費用分攤（Cost-sharing）。
