I think you misunderstood the gp. The problem is you don't know what you pay for. It's pretty much impossible to tell for a normal person in what different ways a flight A and flight B will shaft you to edge out more profit. This doesn't just apply to planes - we are long past where price has anything to do with quality.

There really need to be bettwer laws for making sure customers are fully informed of what they are buying. This goes extras for things like cheap flights where you are essentially gambling.
