The Committee for a Responsible Federal Budget alerted us last week to a troubling (if predictable) trend. With jobs scarce, far larger numbers of workers are applying for Social Security disability benefits. Presumably, this is the result of both the increased incentive to commit fraud and the reality that marginally disabled low-skilled workers have virtually no chance of finding employment in a market full of able-bodied unemployed. Once in, by the way, the incentive structure makes it unlikely recipients will ever get out: to collect benefits, you can’t work at all. Not surprisingly, just one percent ever return to the job market.
