SO, what was uranium used for?
Well, according to a sign in the park, it was used as a topical ointment for many ailments, from arthritis to gangrene.
As the sign said, the "cure" was worse than the problem.
I thought about that as I read the following regarding vouchers:
In the end, snake oil is snake oil. When you can't explain what's in it, what's good about it, what objective studies and consumer reports have concluded about it, I suppose all you're left with is the argument that trying it can't make things any worse. And that's not an argument at all, it's a fallback position.
