Cactus, I would have thought that those of you from the 'Land of the Free' would be aghast at the thought of a restricted economy a la (former) USSR. In a free market, airlines like Southwest and other LCC's are just the economic leveler. Blaming them is just barking up the wrong tree. Try persuading the travelling public instead. It's their dollars that dictate the market. If you're not careful, it could be Roubles dictating instead.
It's not a nice thought but it is the way of our capitalist society with the free market economics that give you and the rest of us the choice of flying LCC or Full Frills schedule. Your anger at the effect the LCC's are having on the majors is misdirected.
