The solution is simple-This system (pressurisation) IS one that requires serious monitoring because any problem with it, at altitude can result in death, for all on board. Aircraft capable of ceilings above 14,000 ft used to carry a flight engineer, a systems man and pressurisation was one of the prime systems. Now, this system is supposed to be "Automatic" but then -other systems that have that same degree of reliance, are monitored in a better way, than that of pressurisation. If cockpit management was updated to include regular monitoring of that system and there was a little mor instrumentation put in to show flow and outflow valve condition, this would go a long way in to making a safer operation.
