The Supplemental Security Income program (SSI) was created in 1972 under the Nixon administration to provide financial support to low-income seniors and disabled people. An effort to federalize state-level adult support programs across the country, SSI is a means-tested program—there are financial requirements to be eligible. In the case of SSI, as of its last adjustment in 1989, enrollees cannot have savings of more than $2,000 as an individual or $3,000 as a family. Furthermore, SSI beneficiaries are prohibited from having retirement accounts, life insurance policies, certain types of personal property, funeral/burial policies, and access to other types of income.

OMG I'm gonna test some means! 
I hate this country, this reminded me of last year before my mom died. when she got injured from her workplace, she tried to apply for disability and got denied. and she was worried of going homeless from all her medical bills. she was thinking of getting a disability lawyer to help with this, but her health ended up declining very fast before she could get to that
I'm so sorry, comrade.
Anecdotally, from a friend of mine, everyone gets denied on their first disability application. An attorney is a de facto requirement. Probably intentional in order to cull the numbers. Wonderful system.
