As one of the oldest welfare states, Germany also has one of the most highly effective social systems. Through social security programs, the state protects its citizens against risks such as the need for long-term care, unemployment or illness. The social security programs are based on two main principles and the five so-called branches of the social security system.
The first principle is the principle of mandatory insurance coverage. This means that social security is obligatory for every German citizen. The second principle of solidarity means that, depending on the income level, all insured persons have to pay into the social security system, even those who have not claimed any benefits. In this way, those citizens who have claimed benefits can be covered by their fellow citizens.
