Another Reason To Reform Welfare?

Since we now use electronic transfer of welfare benefits to people who get welfare, like food stamps, general welfare and unemployment compensation, how do we know if people still live, or have ever lived at the address they have listed.  Well, in Massachusetts, they found or actually, cannot find, 19,000 welfare recipients.
From the Boston Herald: Red-faced state officials admitted last night they are trying to find as many as 19,000 missing welfare recipients — after the controversial taxpayer-funded voter registration pitches the state mailed to their addresses last summer were sent back marked “Return to sender, address unknown.”
The Department of Transitional Assistance contacted 477,000 welfare recipients who were on their books from June 1, 2011, to May 31, 2012, after settling a voter-rights lawsuit brought by Democratic-leaning activist groups that demanded an aggressive voter information effort by the state. That $274,000 push by DTA resulted in 31,000 new voter registrations — but revealed an alarming number of welfare recipients whose residency in Massachusetts can’t be confirmed.
“DTA is in the process of contacting those clients for which a forwarding address was prov­ided to verify their addresses, as a change of address might impact their eligibility,” a statement from the agency said.
DTA critics expressed astonishment at the agency’s faulty address records — which were only uncovered by accident — saying it’s further evidence that the electronic benefits system sorely needs reform.
“Wow,” said state Rep. Shaunna O’Connell, R-Taunton, upon hearing of the number of 
returned mailings.
“The fact that 19,000 of these came back undeliverable tells me DTA has no idea where these people live, obviously, and is not doing the background checks they should be doing,” O’Connell said.
“It goes to show this program is just fraught with fraud and abuse and needs a complete overhaul,” said O’Connell, who has made her name on Beacon Hill as a leading legislator for welfare reform.
It was not clear last night how many of the missing clients have moved out of state or are otherwise no longer eligible to receive Massachusetts benefits. http://bostonherald.com/news_opinion/local_coverage/2013/01/welfare_recipients_%E2%80%98missing%E2%80%99
I wonder if they did this in Nevada, especially in Clark County, what the results would be.  I think the results probably would be the same or worse, especially since we have such a high rate of people moving in and out of Nevada on a daily/monthly basis.
