They only take up a business or first class seat when that seat is determined by the airline to otherwise go out empty. The marginal cost of food and alcohol is minimal and more than made up by being able to resell the original economy seat. Similarly any costs related to lounge use is also recouped by the resale of the original economy seat. So "Bottom Feeders" are actually beneficial to the airlines, not a liability.
