The real evil aren't non-freq fliers that rack up a points on credit cards. It's many people like me and others here at FT who only fly LUT fares, rack up miles, and snag saver award a year in advance, before you or the million+ banked mile rich person even thought of taking a vacation. People like me can do as much damage to seat inventory as one of OP's supposedly-rich antagonists, with only half the miles.
