There is no "benefit" in the Ponzi scheme known as SS unless the government is taking nothing from you.
I promise you this....the socialist is not thinking of a commensurate increase in "benefits" if the "tax" is raised. He wants to give that money to those who are not working or he wants to give that money to people making low wages. That's the "benefit" he's thinking about.
To make Social Security solvent we have to increase “contributions” well beyond the maximum benefit? Sounds more like a special income tax at that point.
