The political left is adept at creating non issues and then using convoluted arguments to solve an unrelated problem.
When someone (including me) says Social Security is going broke they mean the trust fund is being depleted to zero in about sixteen years.
However, Social Security will go on paying some level of the earned and promised benefits, about 75% +- . That is supposed to be good news?
Up until 2010 incoming payroll taxes over those needed to pay benefits were placed in the trust which invested the money in Treasury bonds paying the trust interest (3% give or take a few points). The trust also gets revenue from the income taxes some beneficiaries pay on 50% of their SS benefits.
Today all incoming payroll taxes, all interest payments, all income taxes plus the redemption of some of those Treasury bonds are needed to pay 100% of the benefits earned.
Only a shortsighted or very naive person would declare that a sound fiscal footing. And yet, that scenario receives a positive spin from Sen Sanders and friends and even the claim Social Security has a surplus which can be used to increase benefits.
We have no business talking about increasing benefits until we first make Social Security sustainable as it is. That means higher taxes on all workers and/or modifications to the program.
And for the record, nobody has ever talked about cutting the benefits currently being paid to beneficiaries.
