Menekse pretty much summed it up. EU is taken over by low cost airlines that dictate TC's. They are clever and their scheme rely on endless supply of fresh pilots and shady contractor agencies. Whenever they feel they need more pilots they prefer not to improve TCs but rather lower enty requirements and get influx of zero hour pilots bonded for TR and dumping cycle repeats itself constantly.
1500 h rule is not an option for EU. It might cause low cost model crash with bankruptcies and redundancies. Of course there could be compromisible solution but why bother if everyone is happy and system works more or less. Untill unlucky 250 h instagram cowboy cfits 3 nm before touchdown nothing will change.
