Married or single, there are better options. Might not pay as well, but if that's the prime motivation for working for EK then that's that, I guess. If anything I can't even imagine functioning with any normality at EK with the additional challenges of family life, let alone single.
My friends kids cry every time they see him in uniform, because they know he's about to leave again after his "Dubai layover". When they come and jump on him at 7am after he's been asleep for a couple of hours they can't understand why he's too exhausted to play with them. Etc. If there was some hope that it might eventually improve, that would be something. Good luck, the trends are clear.
And yes, I concede the decisions are harder if you're married and have children. But hey, you make your choices and you live with the consequences.
