Incorruptible, you are claiming massive abuse: Yet, you've done nothing to support that statement.
Dozens, out of 200 MILLION does not equal massive.
And, if you had half a clue, you would realize that we would need to spend MORE money on welfare to fund more people to investigate fraud. While I agree, and I doubt that anyone in this thread disagrees that people shouldn't be abusing the system. But, if it only amounts to dozens out of 200,000,000 transactions, then the cost of fighting that limited abuse would exceed the amount wasted through that abuse.
It's much the same as the marijuana users on welfare in Florida - Florida spent far more money testing people than it saved by finding a few people who used marijuana while on welfare. As such, I don't want them spending $2 of my tax dollars to save $1. Since you appear so burdened by this entire thing, perhaps you'll chip in more of your own money to help fight it. Seriously - donate extra money to the government with a note "please spend this extra money to fight welfare fraud." I mean, if that's the way you really feel about it, then you should be willing to do that. Else, you should shut the hell up about other people staying within the law when they pay their own taxes (and not paying extra out of principle.)
