I've been laughing every time I see some senator or whoever on TV today questioning why oil companies have had record profits this year. These record profits mean they are paying record tax rates -- windfall profit tax when they are already paying close to a 50% tax rate?? This isn't the 1970s, these guys need to stop making fools of themselves and pick up a real economics book.
