Exactly. A disabled guy collects $908 a month which is 10896 annually, with housing and food stamps it comes to $18744 annually. The difference of $7848 annually is social services to allow survival and to keep all those social service employees employed. Figure 56.7 million disabled people in the USA(0), that's a lot of cake. $445 billion on top of the disability checks. I think this would cover the cost of the program plus save a bundle on social service employment. Average social worker earns $45,000 annually(1). 649,300 social workers (1) (2014) totals $29.2 billion.
I don't believe we could eliminate all the social workers, but a substantial number of them.
