What's "reasonable" is in the eye of the beholder (or is it in the eye of the man on the Clapham Omnibus?).
I don't think I nominated any of those scenarios as "reasonable" and to be putting those sorts of hours in as I near 40, with a couple of kids, is not something I aspire to
...it's just that plenty of people do it.
I know a dozen guys my age (none of them pilots) who are living on the North Shore of Sydney in a $2m+ house, making bonuses of $200k every year, and never seeing their kids, which is one reason I live outside Sydney and shall do so forevermore
