Who's going to decide which trip is useless and which is not? The market has clearly decided that it is more profitable (hence useful) to offer cheap flights in not-so-great conditions for mere mortals than elite service for few. And those with money can get better service if they need it anyway. Mass killings of useless people would help stop global warming as well. Why don't do that and leave only those worthy of living. Great idea, isn't it?
