Social insurance contains which kinds of insurance, useful

Social insurance includes five types of insurance, including pension, medical, unemployment, work injury and maternity.

Each of these has its own usefulness, and this is the state mandatory unit to employees on, of course, the employee must also have a certain percentage of self-responsibility.

As to whether there is no use, I find two questions to ask you understand.

When you retire in the future, everyone else can receive a monthly living expenses, even if the food is not good drink is not good, but at least food and drink is not worried. If you do not have this money, are you willing? What do you do?

If you retire in the future, sick, others can reimburse a lot of medical expenses, you see the doctor all out of pocket, a cancer will be more than a few hundred thousand, you are willing to?
