Refinement, n., The essence of culture and good taste.

2008 GW BUSH 17 Jul. "The other thing is that -- I'm sure you know this, April, but we haven't built a refinery, a new refinery in the United States since the early '70s. It makes no sense. And yet you try to get one permitted, it is unbelievably difficult to do. People aren't willing to risk capital if they're deeply concerned about how their capital is going to be tied up in lawsuits or regulations. And we import a lot of gasoline, refined product from overseas."
