I don’t think she would qualify for survivor’s benefits unless she was rearing a minor child. However, she would be eligible to get widow’s benefits when she reaches full retirement age (or reduced benefits as early as 62), and it would be her deceased husband’s whole benefit, not just half of it.
She can draw half if he’s still living and drawing his whole amount.
If he dies and she’s under 62, she’ll just have to find a job for a few years.
A surviving widow can begin benefits at 60 with a reduction in benefits compared to 62. Limited government is a foreign policy here at FR these days. Even tiny steps are met with loud roars if opposition.
