There's nothing special about it. I'm a software developer, like a lot of people on HN. My dad did the same thing, and he was a salesman. I know a lot of people who are able to make it work.

Yes, it's expensive, and it's getting harder as prices begin to reflect the dual-income status of a lot of middle class families, but it's not that difficult if you're willing to make some basic compromises. Consider that it's all relative. I think my life is pretty nice as-is, and that's what matters.

I would say that it's a lot easier if you don't live in SF or another city with an atrocious cost of living, but really in SF and NY you need a sextuple income to afford a liveable place, so the point is kind of moot anyway.
