Airline madness

Is anyone else perplexed by the supposedly rational and sane methods with which the airlines assign pricing--that same rational and sane methodology that is actually totally and completely arbitrary and designed to rape as many people as possible?!? Boo to ass raping, I say! Why the fuck is it $100 CHEAPER for me to leave ONE DAY later, both days mid week? Because of course, I CAN'T leave one day later, and the airlines, behind their shroud of innocence, somehow KNOW that I can't leave one day later and just want to taunt me with a cheaper ticket and laugh as I don't purchase it. Boo to that shit.
