I totally agree. It's not kind of hard physical work but you are paid for 12-14h duty. During this duty you are responsible not only for 50m> $ aircraft but also for 200 pax behind you+there are many decisions to do except how many kgs of extra fuel to take.
Most of the pilots who say it's easy job are totally out of the loop once flying. I have seen pilots watching movies or playing games on a phone as soon as they reach cruising altitude and totally loosing situation awareness what is going on around them. They are doing it as they think their job is easy so what to stress about, autopilot is flying anyway by itself...
