Let's see,
The OP points out that a good many people approaching retirement haven't saved any money for their retirement years.
Skull Pilot argues that if people were not required to pay into Social Security they would be able to invest the money taken from them and built a nice nest egg.
Is it fair to assume those who didn't save, wouldn't invest?
So who benefits if Social Security is no more?
1. Employers
2. Insurance Companies
3. Banks
4. The Bernie Madoff's and other cheats
5.. Pawn Brokers
6. Stock Brokers
7. Plutocrats & the 1%
8. The investor class
who will be screwed? The same people who live on Social Security today, and won't have even that small amount to survive on. Thus, the taxpayer will provide food, clothing and shelter.
Look back at census records prior to the advent of SS. If you do you will see a good many people living in large abodes, those abodes were the poor houses.
But, keep in mind, the power elite in America will be in control of the laws, and the Plutocrats are the 1% who will write tax laws to their advantage.
