only the regulator can ensure basic flying experience levels rise.
In France at least it was the regulator who decreased the basic flying level since 1979 and deregulation - it is the true and official name of that movement- didn't work for low cost airlines first but for Air France competitors to destroy the SNPL power... These airlines at the beginning were not low cost in the today's sense but they only decreased the bill cost by flying only the trips where Air France and Air Inter were full of passengers (Paris-Antilles, Paris-Nice, Paris-Toulouse, aso) or low level fuel price trips (Marc Rochet).
The decreasing level of formation started with A320, remember the strikes of AEROFORMATION FTEs unhappy to have no more enough time for basic and classical flights, they had to use the time to teach B.A.BA of FBW button pushing.
Low cost airlines could only emerge in France when it was no more mandatory that a French airline used a French registered plane, and leasing helped to share benefits in one hand, financial risk in another... and fisc didn't see the loss of money and corrupted people organised financial worldwide Mafia hidden behind the ICAO flag.
