How many people do you know who could not live without their social security check?

I am only interested in retirement age social security. Not disability or other benefits.

Whether the person relies on socal security for all or part of being able to pay their expenses it counts for this question. If the person(s) would be able to live on less just change their lifestyle that would be a different category than having to live on the street or move in with relatives who would support them.

If people never had social security or we did away with it, do you think people would save better for the future themselves? I know historically social security brought many seniors out of poverty, do you think knowing the history would mean in present day more people would save for the future. That there is so much information out there more masses of people would take necessary steps.
