A proposal for an unelected, life-term legislature

Last I looked, when you have a political entity that serves for life, is unaccountable to the people, and can do anything it wants, you had a monarchy or, if it was a bad monarchy, a dictatorship. What's scary, though, is that this is precisely how Justice Breyer envisions the role of Supreme Court justices. He speaks in terms of Democracy, and appears utterly unaware of how profoundly undemocratic his impulses are -- impulses that would ultimately consolidate all power in the hands of 9 people who would have no constraints on them at all. Scary, very scary.
