Well, yeah, that's news from the files marked "Duh."
But white southern republicans often don't know this, or intentionally ignore this. They seem to think that if you let people use the system, they'll abuse it. What they don't understand is that the people who abuse the system are a very small fraction, while most people use it when they need it and then work hard to never need it again. So what, we should eliminate the system because some people abuse it? That hardly seems fair to those who use it properly, and my guess is that the people who would abuse it would find other way to scam someone or some organization so no problem would be solved.
