Same old clap-trap been touted for decades.
This entire article is deeply dumb.
Social Security is a tax.
Then it is a government expenditure based on whatever criteria Congress chooses or delegates to the Social Security Administration.
There is no “solvent”.
There is no “saving”.
That is accounting silliness.
Government can tax as it wishes and spend as it wishes and call the taxes Unicorns and the expenditures Unicorn excrement if it wishes.
