Also, one of the reasons using the stock market for SS funds was a bad idea decades ago was because the rate of return for SS was much higher than the stock market could achieve.
That has now completely flip-flopped and is true no longer.
We are talking single digit numbers here, like less than 2% -

Another issue is the imbalance of proportions when comparing immigrants to natural citizens. You get a much higer rate of return if you move to this country compared to paying into the system most of your life. I'm not against immigration, but the person who paid into all of their life should benefit more than the person that has just moved here--that is hardly "fair".
