Not all airliners. If you have the oportunity to assist to an, for instance AF's FA briefing before departure, sometimes even w captain directing it, you will note how serious they prepare as a whole crew and individually, in each station, how they stablished the procedures, who is in charge, assign personal tasks. How they check all the emergency equipment for availability and proper working condition, how they demand and even stop the flight should something is missing or malfunctioning.
At that time, no other problems like maintenance, catering, operations will be adressed, only passager and crew safety. This requieres time, training, discipline and, of course, money. In my experience, this is very similar for many full fare airliners
I had not any experience neither I expect such a meeting in a LCC.
At the end, everything goes down to "You get what You paid for".
