How about “rational rant?”

I think George Carlin invented the oxymoron-as-one-liner, starting with “jumbo shrimp” and “military intelligence.” He would have loved the last few weeks, when he could have added both “legislative decision” and “business ethics” to his shtick. And we're not talking about folks trying to get way with breaking the law of the land, but the very laws of thermodynamics. Unlike government, nature never looks the other way. That's why Ponzi schemes, Amway memberships, investment bubbles, and - I'm thinking - the very concept of capital itself are fundamentally unsound. The most absurd oxymoron of them all is “sustainable growth.”
