Heh. Flying is a terrible experience because what most people pay for is the transportation equivalent of a Wal-Mart jar of pickles.
The price of flying, especially as a proportion of income, has tanked since the golden age we all yearn for. There's a reason airlines no longer serve meals, give out free pillows, and are still going bankrupt every few years - the margins are razor thin and the competition is extreme.
It's the same reason why they no longer hand out hotel rooms like candy, or why there are more cascading delays (hint: keeping spare planes and crews on standby is really, really expensive).
If you paid as much now as you did for the same flight in the 70s, you'd still get the very same service.
