Aside from being tied to the CPI, sounds unnecessarily complicated. And I don't know if it's shoddy reporting or Hawley being incompetent, but SSN doesn't imply citizenship. A person legally working in the US gets an SSN so this just sounds like red meat for the base and is either a possibly unconstitutional requirement or a lie.

The article does correctly note that this would basically shovel federal tax money into states that didn't raise the minimum wage.
