I have also been telling my kids not to take up a career as a pilot, mainly due to how volatile a career it is and it's much easier said than done to have a viable backup plan. Unless you can keep your hand in with a second profession throughout your flying career it's going to be very difficult to fall back on a previous career, experience or education when it's 10+ years out of date (even more so in todays job market). For that reason, I hope permanent part time contracts become more easily available ro those who want them. They could give pilots a fighting chance to diversify on the side. A couple of colleagues managed to build a property empire on the side and now have a second income to give them some breathing space...great idea if you can afford the initial capital.
All that said, I still know of medics, lawyers and teachers who tell their kids never to take up their parents chosen professions for various other reasons.
