The U.S. federal government created the Social Security program to support some of our nation's most vulnerable people -- the ones who are disabled and unable to earn an income for themselves. Through the Social Security Disability benefits program, someone who is too ill or disabled either physically or mentally can file an application to receive helpful financial support that enables them to be independent members of society.
Not all disabilities are obvious, and not all disabilities are physical. There are many mental disabilities that impact people in the United States. These individuals may not be able to work, just like someone with a physical impairment may be unable to work.
