Social Security and Medicare: insurance against low income after retirement.
Medicaid: medical insurance for the poor.
Germany became the first nation in the world to adopt an old-age social insurance program in 1889, designed by Germany's Chancellor, Otto von Bismarck.
The idea was first put forward, at Bismarck's behest, in 1881 by Germany's Emperor, William the First. Bismarck was motivated to introduce social insurance in Germany to stave-off socialism.
Germany initially set age 70 as the retirement age.
The United Kingdom enacted national medical insurance in 1911, expanded in 1948.

2. Efficiency. The private insurance market is accused of failing to provide efficient policies.

Except credit default swap derivatives.
A credit default swap (CDS) is similar to a traditional insurance policy, in as much as it obliges the seller of the CDS to compensate the buyer in the event of loan default.
Generally, this involves an exchange or "swap" of the defaulted loan instrument (and with it the right to recover the default loan at some later time) for immediate money - usually the face value of the loan.
However, there is a significant difference between a traditional insurance policy and a CDS. Anyone can purchase a CDS, even buyers who do not hold the loan instrument and may have no direct "insurable interest" in the loan.
The buyer of the CDS makes a series of payments (the CDS "fee" or "spread") to the seller and, in exchange, receives a payoff if the loan defaults
