From Does Welfare Prevent Crime? The Criminal Justice Outcomes of Youth Removed From SSI by Manasi Deshpande & Michael G. Mueller-Smith (emphasis added):
We estimate the effect of losing Supplemental Security Income (SSI)
benefits at age 18 on criminal justice and employment outcomes over the
next two decades. ... We find that SSI removal increases the number of criminal charges by a
statistically significant 20% over the next two decades. The increase in
charges is concentrated in offenses for which income generation is a
primary motivation (60% increase), especially theft, burglary,
fraud/forgery, and prostitution. The effect of SSI removal on criminal
justice involvement persists more than two decades later, even as the
effect of removal on contemporaneous SSI receipt diminishes. In response
to SSI removal, youth are twice as likely to be charged with an illicit
income-generating offense than they are to maintain steady employment
at $15,000/year in the labor market. As a result of these charges, the
annual likelihood of incarceration increases by a statistically
significant 60% in the two decades following SSI removal. The costs to
taxpayers of enforcement and incarceration from SSI removal are so high
that they nearly eliminate the savings to taxpayers from reduced SSI
benefits.
You've been granted SSI disability benefits as a child. It wasn't easy. You had to have been pretty sick. However, at age 18, even though you haven't gotten a bit better, you're made to prove all over again that you're disabled and in many, many cases cut off your SSI, leaving you with no income. Why? Does turning 18 make people healthier? How can we realistically expect anything other than bad results from such a brutal policy? This study is looking at just the dollar costs to the government. What about all the misery caused to disabled people and their families? That has value too.
