Social security provides the principal source of retirement income for the majority of people in the United States, this includes those who receive pensions through employer sponsored plans .
During the 1700`s and early 1800`s many people industrilized . This allowed people from rural areas to migrate to cites and work in factories . A majority of these people received low wages and had to work under treacherous conditions . Due to these extremely low wages people were unable to save for retirement . If any of these people were disabled on the job or even were fired from the job there families had to suffer greatly . So due to the industrial revolution social security insurance began in the United States . Social security was not developed in the United States though it was known before it began in the United States . Social security first became known in Europe.
Social security is a government program that pays retired people a certain amount of money. Social security is also called social insurance because it doesn't only cover retired people but also to disabled workers , to the families of workers who have retired , become disabled , or died ; and now also for medical expenses under Medicare .
