You can't blame passengers who want cheap flights.
Passengers assume flights operate under a set of guidelines that are there for their safety. They then buy the cheapest flights available to them that get them from A to B. If the airline that sells the cheapest flights then can't balance the need for airline safety and profitability, they either then lose money or cut corners on safety.
NEITHER of these issues are attributable to the passenger. BOTH are issues solely lying with the airlines. If the airline is going to cut corners rather than lose profitability, then THAT is what needs investigating, NOT laying the blame on the spurious notion that passengers are playing Russian roulette with their money.
