'What to do?', without wanting to answer for Luddite, you're taking a very short sighted view of aviation.
For a start, not all pilots are employed in the airline sector.
Also, things look rosy at present. But in this cyclical industry, losing one's job is very common. Again and again. That sure eats into any savings you may have.
The industry can put a lot of pressure on a marriage - divorce isn't cheap.
So ending up with an old Volvo and no financial buffer is very very easy.
That's how you 'manage that then'.
