Not important at all, but staying at a shitty job for years at end (well, unless you're a student, in which case there's a very high chance you'll get a decent job after you finish education, so it's fine flipping burgers until then) pretty much signifies having no ambition and skills. And that is not something I'd want in a partner. Or if they are sort-of ambitious, but unmotivated (slightly contradictive, but not entirely - one can dream of doing something, but can't get around to actually take a step towards their goal) or do possess some skills, but don't bother working? Well, I wouldn't want a lazy partner either.
So, I don't care about just being rich. Hell, I dream of becoming a teacher, so I'm well aware I'll be earning peanuts, but that's a purpose in life and that's what matters to me. If I can find a woman similar to me who'd also happen to be interested in me, well - on that day I'll be a happy guy. Not very likely in these times, though.
