I assumed so. I don't know why you think that you are somehow investing in something "everyone owns" with FICA taxes. The government is not "investing" in anything on our behalf in Social Security.
This is where political language gets tricky - Conservatism in the American tradition is focused on defending the Classic Liberal values of our founding. That is a
far cry from Bismark, who, in American parlance would not fall under "Conservativism" but "Progressivism", which is why our early 20th Century Progressives here were so enamored with his systems.
A certain amount of private sector activity is necessary and beneficial. I'm not a huge fan of privatized prisons, but, I also have no problem with Wal Mart catching shoplifters.
This sounds suspiciously like the "MMT" nonsense - is that what you are trying to propose here?
Governments' can make investments - ours does not, at least, with FICA funds, though that is something I am trying to change.
However, governments can indeed run out of money, even after that money has become effectively worthless because of overproduction. What do you think happens when it costs more money to print the money than you can print?
I've shown you the math - I had hoped you were going to engage with it
. You seem to prefer not to.
