Self-selecting for this type of employee is also a problem. I can understand doing this for the first few months when you're trying to bootstrap, but long-term if your business model can't scale without people working 12-14 hour days, your business model doesn't scale.

We all read articles on HN and HBR saying that more hours != more work, but we still hire for it anyway. I know most founders are just looking for passionate people who fit with their team, and it can be hard to build a team when one of your team members has to leave every day at 3:30 to pick their kids up from school. But we should at least try to be better.
