It's kinda of... I don't know what the right word for it is - how as corrupt and incompetent as our government has proven to be, so many people still want to put it in charge of our healthcare, or more so than it already is.
I guess it's the desire for more "free" stuff. It's kind of like voluntary imprisonment - you trade in your freedom, the free stuff is crap, and somebody else still ends up paying for it, but it still seems to make some people happy because it's "free" to them. The problem is that they want to impose the same shitty system on everybody else (how else would it be paid for) and most people (I hope) would rather work for a living, enjoy the fruits of their labor, etc.
