All their working lives, everyone has paid and are currently paying directly into the social security system through payroll deductions. Between ages 62-65, this becomes a part of their retirement plans. Since their payroll earnings fund social security, such folks have legal "entitlement."
People do not work to pay into the welfare system. That's a handout funded by illegal taxation forced on the people by the federal government. Welfare is not an "entitlement" for anyone.
To mention the two in the same breath [and politicians do it often] is an insult to social security.
