Yes, you are an aviation snob. I advise that you travel EZ, FR, LS, WW etc, before you condemn them all as unsafe and awful. They are really not.
The choice to fly the legacies is still there (in fact, who operate more competitively themselves THANKS to the locos), but it is a simple case of free market. If there is demand for high level service (I'm not talking safety), then these companies will attract business and make profit. If not, they will adapt their product or go bust.
It seems like we've had this debate a million times before in this forum. Airlines set out to meet demand in order to turn a profit. The "ruining" of the industry could only be considered the consumers' fault, rather than the airlines who have exploited these niches.
I do wish EZ would change its livery though! Their new grey and orange corporate colours would look brilliant on their A319s!
