The job of flying an airplane is still fun, however that is alas only a small part of being a commercial pilot.
If i had a son i would discourage him from going into aviation, only exception if he would be accepted by Lufthansa into their cadet program. Apart from that it is better to go to university, get your masters and then earn some nice money in another job. With around 30.000 open places for engineers alone over here in germany and an increasing demand on academically trained personal the future looks quite bright. And one can earn enough money to fly some real fun airplanes on the side, those that do not complain if they are flown upside down, or without an engine, or both
That said i would encourage him to start glider flying at 14, since it is an absolutely superb and pretty cheap hobby.
