It depends on what "hardworking" means.

Are you at an entry-level position for a job that will eventually make decent money? Are you working really hard at a lot of jobs that, in all honestly, don't have much of a future? Do you work with your hands at something like construction, electrician-ing, or oil-rig-running?

Some people want a certain level of income in their lives. They might not want to spend their lives poor, or they might just want to keep whatever quality of life they've grown up with. So, unfortunately, if you're 27 and working at Wal-Mart, that's probably not going to get them where they want in life. That's not wrong, provided they're also willing to work -- it's just two people having two different and incompatible life goals.

If you're a hard worker in a field that might not make a lot of money but which is also dangerous (which is true for quite a lot of jobs), the other person might not like that element of danger. I could probably never seriously date a soldier, a firefighter, or a cop. I don't think I could handle not knowing if my SO was coming home at night. Likewise, some people don't want to worry about whether their SO got their skin melted off by a faulty wire or crappy supervisor, or got their arm chopped off by something falling, or got lung cancer from breathing in hazardous dust (the kinds of injuries not that unheard of amongst those who work the skilled trades). That's not the other person's fault, either.

If one person (regardless of gender) has a certain place they want to be in 10, 15 years, and you don't fit that plan -- even if it's just because you don't make enough money and probably won't start making that money -- it's perfectly reasonable for that to disqualify you as a partner. It's not just about the money, it's about life goals.
