This is one of the most out-of-touch HN comments I've seen in a while. Most people are not nearly as privileged as the community on these forums. Not even all the people posting here are fully removed from the risk of being out on their ass. Some have moved from other parts of their home country (think people in the Bay Area who moved for a job and have no family in the same job market). Some have moved from other parts of the world to where they are and have no one upon whom they can impose. Plenty have huge student loans and are so fresh out of school that they're at the edge of the many rounds of layoffs affecting the tech industry in the last few years and lack enough experience on their resumés to land a new position before their finances run out.
I can't believe how tone deaf it is to suggest that most people have multiple rungs upon which to fall back. And I've only been talking about people on these forums, the "fortunate" types.
