Actually no.
As a citizen of our still free country I find it offensive and an intrusion of privacy to single out one group of people. Shall we also test those collecting retirement benefits?
As a nurse I find it another waste of tax payer money as the majority of Americans (from what I see) are on some form of drugs be it prescription or street drugs.
What I would support is limiting assistance to maybe a year like it was intended in the first place and not as support for life which is one reason our country is in the mess it's in.
On the other hand I think it's too late to fix things. With the shape the economy is in I don't believe there will be assistance much longer. The funds are just not there. A good thing was abused by way too many with no controll just as in many other areas of govt and now the bucket has run dry.
