"Where will the money come from to get the car fixed?" is a very personal question; answering it well would require knowing a lot about the person asking, and what their life circumstances, talents, resources, and obstacles were. This makes it harder to discuss on HN (or most other Internet sites), since these are very large groups who are mostly strangers, and don't know that much about each other. Questions about economic equality, the cost of housing, career advice, and so on in general are reasonably well represented here, I think.
There are different questions that we have at each level in Maslow’s pyramid, and HN tends to focus on the last two levels - but that doesn’t mean the questions at the other levels are any less important. There are other site, communities and blogs that cater to people at these levels.
A one size fits all solution wouldn’t be good for any of the levels, and it doesn’t mean people are one level are any better or worse than people at others.
