Most significantly, it would immediately boost benefits by $200 a month for every Social Security recipient. If the plan were implemented next year, the typical beneficiary would receive $1,595 a month, rather than $1,395. It would also increase monthly payments by $200 for certain Supplemental Security Income recipients, who are low-income seniors or people with disabilities.

The plan fits into the presidential candidate’s broader message demanding “big, structural change” to large parts of the American economy and would take significant steps in an attempt to address a legacy of inequality that, she said in a Medium post, has hit older women and people of color the hardest.

The plan arrives just hours before Thursday night’s Democratic presidential debate in Houston, which could spur more in-depth discussions before a national audience.
