This question is confusing, could you word it better?
An agreement among members of a society to cooperate for social benefits
One reason some people support raising the eligibility age for receiving Social Security benefits is that 2. people are living longer today. Social Security is intended to support individuals as they enter the end of their lives meaning they are no longer physically able to provide for themselves. However, with advances in medicine, today's individuals live healthier and longer lives thereby allowing them to work to an older age. Therefore, some believe Social Security should only be accessed once people are unable to work which would be later in life than it was when the bill was passed in the 1930s.
I believe it would be the industrial revolution and the civil rights movement.
The industrial revolution make companies able to improve their production with more machinaries and less slave labors. Which make the usage of slavery became less and less popular in the north. It also allow the construction of railroad for easier distribution system and The civil right movement bring up equality issues between race majority/minority to the law.
