Airlines: You are advised to arrive at the airport 2 hours before your flight is due to take off

Why, is it so you can make hundreds of people drag their heavy luggage through snaking lines before your lazy and inefficient staff finally check them in?  Besides, why don’t you get your own slovenly aircrafts to arrive 2 hours before they are due to take off so that we might experience a one-in-a-million chance of taking off on time?
