Pay to fly is not the main problem in this job. The big problem is salary.
In a couple of years you will see that standard captain salary on A320/B737 will be 4000€/month for 75 hours on avarage, this is the tendency on Vueling, Wizzair, Ryanair, Volotea and so on.
So many young FOs are willing to accept a captain job in those horrible T&Cs.
